+* default: `off`
+* arguments:
+    * `off`: Passthrough is never enabled.
+    * `ro`: Only enable passthrough when file opened for reading only.
+    * `wo`: Only enable passthrough when file opened for writing only.
+    * `rw`: Enable passthrough when file opened for reading, writing,
+      or both.
+
+In [Linux 6.9](https://kernelnewbies.org/Linux_6.9#Faster_FUSE_I.2FO)
+a IO passthrough feature was added to FUSE. Typically `mergerfs` has
+to act as an active proxy for all read and write requests. This
+results in, at times, significant overhead compared to direct
+interaction with the underlying filesystems. Not because `mergerfs` is
+doing anything particularly slow but because the additional
+communication and data transfers required. With the `passthrough`
+feature `mergerfs` is able to instruct the kernel to perform reads and
+writes directly on the underlying file. Bypassing `mergerfs` entirely
+(specifically and only for reads and writes) and thereby providing
+near native performance.
+
+This performance does come at the cost of some functionality as
+`mergerfs` no longer has control over reads and writes which means all
+features related to read/write are affected.
+
+* [moveonenospc](moveonenospc.md): Does not work because errors are
+  not reported back to `mergerfs`.
+* nullrw: Since `mergerfs` no longer receives read/write requests
+  there is no read or write to ignore.
+* [readahead](readahead.md): Still affects the `readahead` values of
+  underlying filesystems and `mergerfs` itself but no longer relevant
+  to `mergerfs` in that it is not servicing IO requests.
+* [fuse_msg_size](fuse_msg_size.md): The primary reason to increase
+  the FUSE message size is to allow transferring more data per request
+  which helps improve read and write performance. Without read/write
+  requests being sent to `mergerfs` there is little reason to have
+  larger message sizes since the only other message larger than 1
+  page, directory reading, currently has a small fixed buffer size.
+* parallel-direct-writes: Not only is `direct-io` and `passthrough`
+  mutually exclusive but since `mergerfs` no longer receives write
+  requests in passthrough mode then there is no parallel writes
+  possible.
+* [cache.writeback](cache.md): FUSE's writeback caching is
+  incompatible with `passthrough`. If `cache.writeback=true` when
+  enabling `passthrough` it will be reset to `false`.
+* [cache.files](cache.md): Must be enabled for `passthrough` to
+  work. When `cache.files=off` FUSE's `direct-io` mode is enabled
+  which overrides `passthrough.` Meaning `cache.files` should be set
+  to `partial`, `full` or `auto-full` to use `passthrough`. If
+  `cache.files` is set to `off` when using `passthrough` it will
+  reset it to `auto-full`.
+
+Technically `mergerfs` has the ability to choose options like
+`passthrough`, `direct-io`, and page caching independently for every
+file opened. However, at the moment there is no use case for picking
+and choosing which to enable outside `cache.files=per-process` (which
+is largely unnecessary on Linux v6.6 and above. See
+[direct-io-allow-mmap](options.md)) If such a use case arises please
+reach out to the author to discuss.
+
+Unlike [preload.so](../tooling.md#preloadso), `passthrough` will work for
+any software interacting with `mergerfs`. However, `passthrough`
+requires Linux v6.9 or above to work.
+
+**NOTE:** This feature will **ONLY** work if `mergerfs` is running as
+`root` as currently only `root` is allowed to leverage the kernel
+feature.
+
+**NOTE:** If a file has been opened and passthrough enabled, while that
+file is open, if another open request is made `mergerfs` must also
+enable `passthrough` for the second open request. This is a limitation
+of how the passthrough feature works.
+
+
+## Alternatives
+
+* [preload.so](../tooling.md#preloadso): Leverages the ability to
+  intercept certain filesystem calls to bypass `mergerfs` for
+  IO. See page for details and limitations.
+
+
+## Benchmarks
+
+Simple `dd` based benchmark on a Hades Canyon (Intel i7-8809G, 32GB
+DDR4-2400 RAM).
+
+```
+# /mnt/test is mergerfs over a single tmpfs mount
+dd if=/dev/zero of=/mnt/test/tmpfile bs=1M count=2000 oflag=nocache
+conv=fdatasync status=progress
+```
+
+Summary: passthrough is ~95% native speed. 200% faster than
+`direct-io` (cache.files=off).
+
+* straight to tmpfs: 1.7 GB/s
+* nullrw=true: 2.1 GB/s 
+* cache.files=off; passthrough=off: 800 MB/s
+* cache.files=auto-full; passthrough=rw: 1.6 GB/s
+* cache.files=auto-full; cache.writeback=false: 518 MB/s
+* cache.files=auto-full; cache.writeback=true: 518 MB/s

+/*************************************************************************
+
+USAGE:
+~~~~~~
+
+Before including this header you must define one or more of define the following macros:
+
+BOOST_LIB_NAME:           Required: A string containing the basename of the library,
+                          for example boost_regex.
+BOOST_LIB_TOOLSET:        Optional: the base name of the toolset.
+BOOST_DYN_LINK:           Optional: when set link to dll rather than static library.
+BOOST_LIB_DIAGNOSTIC:     Optional: when set the header will print out the name
+                          of the library selected (useful for debugging).
+BOOST_AUTO_LINK_NOMANGLE: Specifies that we should link to BOOST_LIB_NAME.lib,
+                          rather than a mangled-name version.
+BOOST_AUTO_LINK_TAGGED:   Specifies that we link to libraries built with the --layout=tagged option.
+                          This is essentially the same as the default name-mangled version, but without
+                          the compiler name and version, or the Boost version.  Just the build options.
+BOOST_AUTO_LINK_SYSTEM:   Specifies that we link to libraries built with the --layout=system option.
+                          This is essentially the same as the non-name-mangled version, but with
+                          the prefix to differentiate static and dll builds
+
+These macros will be undef'ed at the end of the header, further this header
+has no include guards - so be sure to include it only once from your library!
+
+Algorithm:
+~~~~~~~~~~
+
+Libraries for Borland and Microsoft compilers are automatically
+selected here, the name of the lib is selected according to the following
+formula:
+
+BOOST_LIB_PREFIX
+   + BOOST_LIB_NAME
+   + "_"
+   + BOOST_LIB_TOOLSET
+   + BOOST_LIB_THREAD_OPT
+   + BOOST_LIB_RT_OPT
+   + BOOST_LIB_ARCH_AND_MODEL_OPT
+   "-"
+   + BOOST_LIB_VERSION
+   + BOOST_LIB_SUFFIX
+
+These are defined as:
+
+BOOST_LIB_PREFIX:     "lib" for static libraries otherwise "".
+
+BOOST_LIB_NAME:       The base name of the lib ( for example boost_regex).
+
+BOOST_LIB_TOOLSET:    The compiler toolset name (vc6, vc7, bcb5 etc).
+
+BOOST_LIB_THREAD_OPT: "-mt" for multithread builds, otherwise nothing.
+
+BOOST_LIB_RT_OPT:     A suffix that indicates the runtime library used,
+                      contains one or more of the following letters after
+                      a hyphen:
+
+                      s      static runtime (dynamic if not present).
+                      g      debug/diagnostic runtime (release if not present).
+                      y      Python debug/diagnostic runtime (release if not present).
+                      d      debug build (release if not present).
+                      p      STLport build.
+                      n      STLport build without its IOStreams.
+
+BOOST_LIB_ARCH_AND_MODEL_OPT: The architecture and address model
+                              (-x32 or -x64 for x86/32 and x86/64 respectively)
+
+BOOST_LIB_VERSION:    The Boost version, in the form x_y, for Boost version x.y.
+
+BOOST_LIB_SUFFIX:     Static/import libraries extension (".lib", ".a") for the compiler.

+// Cray C++ compiler setup.
+//
+// There are a few parameters that affect the macros defined in this file:
+//
+// - What version of CCE (Cray Compiling Environment) are we running? This
+//   comes from the '_RELEASE_MAJOR', '_RELEASE_MINOR', and
+//   '_RELEASE_PATCHLEVEL' macros.
+// - What C++ standards conformance level are we using (e.g. '-h
+//   std=c++14')? This comes from the '__cplusplus' macro.
+// - Are we using GCC extensions ('-h gnu' or '-h nognu')? If we have '-h
+//   gnu' then CCE emulates GCC, and the macros '__GNUC__',
+//   '__GNUC_MINOR__', and '__GNUC_PATCHLEVEL__' are defined.
+//
+// This file is organized as follows:
+//
+// - Verify that the combination of parameters listed above is supported.
+//   If we have an unsupported combination, we abort with '#error'.
+// - Establish baseline values for all Boost macros.
+// - Apply changes to the baseline macros based on compiler version. These
+//   changes are cummulative so each version section only describes the
+//   changes since the previous version.
+//   - Within each version section, we may also apply changes based on
+//     other parameters (i.e. C++ standards conformance level and GCC
+//     extensions).
+//
+// To test changes to this file:
+//
+// ```
+// module load cce/8.6.5 # Pick the version you want to test.
+// cd boost/libs/config/test/all
+// b2 -j 8 toolset=cray cxxstd=03 cxxstd=11 cxxstd=14 cxxstd-dialect=gnu linkflags=-lrt
+// ```
+// Note: Using 'cxxstd-dialect=iso' is not supported at this time (the
+// tests run, but many tests fail).
+//
+// Note: 'linkflags=-lrt' is needed in Cray Linux Environment. Otherwise
+// you get an 'undefined reference to clock_gettime' error.
+//
+// Note: If a test '*_fail.cpp' file compiles, but fails to run, then it is
+// reported as a defect. However, this is not actually a defect. This is an
+// area where the test system is somewhat broken. Tests that are failing
+// because of this problem are noted in the comments.
+//
+// Pay attention to the macro definitions for the macros you wish to
+// modify. For example, only macros categorized as compiler macros should
+// appear in this file; platform macros should not appear in this file.
+// Also, some macros have to be defined to specific values; it is not
+// always enough to define or undefine a macro.
+//
+// Macro definitions are available in the source code at:
+//
+// `boost/libs/config/doc/html/boost_config/boost_macro_reference.html`
+//
+// Macro definitions are also available online at:
+//
+// http://www.boost.org/doc/libs/master/libs/config/doc/html/boost_config/boost_macro_reference.html
+//
+// Typically, if you enable a feature, and the tests pass, then you have
+// nothing to worry about. However, it's sometimes hard to figure out if a
+// disabled feature needs to stay disabled. To get a list of disabled
+// features, run 'b2' in 'boost/libs/config/checks'. These are the macros
+// you should pay attention to (in addition to macros that cause test
+// failures).
+
+////
+//// Front matter
+////
+
+// In a developer build of the Cray compiler (i.e. a compiler built by a
+// Cray employee), the release patch level is reported as "x". This gives
+// versions that look like e.g. "8.6.x".
+//
+// To accomplish this, the the Cray compiler preprocessor inserts:
+//
+// #define _RELEASE_PATCHLEVEL x
+//
+// If we are using a developer build of the compiler, we want to use the
+// configuration macros for the most recent patch level of the release. To
+// accomplish this, we'll pretend that _RELEASE_PATCHLEVEL is 99.
+//
+// However, it's difficult to detect if _RELEASE_PATCHLEVEL is x. We must
+// consider that the x will be expanded if x is defined as a macro
+// elsewhere. For example, imagine if someone put "-D x=3" on the command
+// line, and _RELEASE_PATCHLEVEL is x. Then _RELEASE_PATCHLEVEL would
+// expand to 3, and we could not distinguish it from an actual
+// _RELEASE_PATCHLEVEL of 3. This problem only affects developer builds; in
+// production builds, _RELEASE_PATCHLEVEL is always an integer.
+//
+// IMPORTANT: In developer builds, if x is defined as a macro, you will get
+// an incorrect configuration. The behavior in this case is undefined.
+//
+// Even if x is not defined, we have to use some trickery to detect if
+// _RELEASE_PATCHLEVEL is x. First we define BOOST_CRAY_x to some arbitrary
+// magic value, 9867657. Then we use BOOST_CRAY_APPEND to append the
+// expanded value of _RELEASE_PATCHLEVEL to the string "BOOST_CRAY_".
+//

+//  Old versions of vxWorks (namely everything below 6.x) are
+//  absolutely unable to use boost. Old STLs and compilers 
+//  like (GCC 2.96) . Do not even think of getting this to work, 
+//  a miserable failure will  be guaranteed!
+//
+//  VxWorks supports C++ linkage in the kernel with
+//  DKMs (Downloadable Kernel Modules). But, until recently 
+//  the kernel used a C89 library with no
+//  wide character support and no guarantee of ANSI C. 
+//  Regardless of the C library the same Dinkum 
+//  STL library is used in both contexts. 
+//
+//  Similarly the Dinkum abridged STL that supports the loosely specified 
+//  embedded C++ standard has not been tested and is unlikely to work 
+//  on anything but the simplest library.
+// ====================================================================
+//
+// Some important information regarding the usage of POSIX semaphores:
+// -------------------------------------------------------------------
+//
+// VxWorks as a real time operating system handles threads somewhat
+// different from what "normal" OSes do, regarding their scheduling!
+// This could lead to a scenario called "priority inversion" when using
+// semaphores, see http://en.wikipedia.org/wiki/Priority_inversion.
+//
+// Now, VxWorks POSIX-semaphores for DKM's default to the usage of
+// priority inverting semaphores, which is fine. On the other hand,
+// for RTP's it defaults to using non priority inverting semaphores,
+// which could easily pose a serious problem for a real time process.
+//
+// To change the default properties for POSIX-semaphores in VxWorks 7
+// enable core > CORE_USER Menu > DEFAULT_PTHREAD_PRIO_INHERIT 
+//  
+// In VxWorks 6.x so as to integrate with boost. 
+// - Edit the file 
+//   installDir/vxworks-6.x/target/usr/src/posix/pthreadLib.c
+// - Around line 917 there should be the definition of the default
+//   mutex attributes:
+//
+//   LOCAL pthread_mutexattr_t defaultMutexAttr =
+//       {
+//       PTHREAD_INITIALIZED_OBJ, PTHREAD_PRIO_NONE, 0,
+//       PTHREAD_MUTEX_DEFAULT
+//       };
+//
+//   Here, replace PTHREAD_PRIO_NONE by PTHREAD_PRIO_INHERIT.
+// - Around line 1236 there should be a definition for the function
+//   pthread_mutexattr_init(). A couple of lines below you should
+//   find a block of code like this:
+//
+//   pAttr->mutexAttrStatus      = PTHREAD_INITIALIZED_OBJ;
+//   pAttr->mutexAttrProtocol    = PTHREAD_PRIO_NONE;
+//   pAttr->mutexAttrPrioceiling = 0;
+//   pAttr->mutexAttrType        = PTHREAD_MUTEX_DEFAULT;
+//
+//   Here again, replace PTHREAD_PRIO_NONE by PTHREAD_PRIO_INHERIT.
+// - Finally, rebuild your VSB. This will rebuild the libraries
+//   with the changed properties. That's it! Now, using boost should
+//   no longer cause any problems with task deadlocks!
+//
+//  ====================================================================

+//  Another resource for understanding libstdc++ features is:
+//  http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#manual.intro.status.standard.200x
+//
+//  However, using the GCC version number fails when the compiler is clang since this
+//  only ever claims to emulate GCC-4.2, see https://svn.boost.org/trac/boost/ticket/7473
+//  for a long discussion on this issue.  What we can do though is use clang's __has_include
+//  to detect the presence of a C++11 header that was introduced with a specific GCC release.
+//  We still have to be careful though as many such headers were buggy and/or incomplete when
+//  first introduced, so we only check for headers that were fully featured from day 1, and then
+//  use that to infer the underlying GCC version:
