 tmpfs also supports Transparent Huge Pages which requires a kernel
 configured with CONFIG_TRANSPARENT_HUGEPAGE and with huge supported for
 your system (has_transparent_hugepage(), which is architecture specific).
 The mount options for this are:
 
-======  ============================================================
-huge=0  never: disables huge pages for the mount
-huge=1  always: enables huge pages for the mount
-huge=2  within_size: only allocate huge pages if the page will be
-        fully within i_size, also respect fadvise()/madvise() hints.
-huge=3  advise: only allocate huge pages if requested with
-        fadvise()/madvise()
-======  ============================================================
+===========  ==============================================================
+huge=never   Do not allocate huge pages.  This is the default.
+huge=always  Attempt to allocate huge page every time a new page is needed.
+huge=within_size Only allocate huge page if it will be fully within i_size.

+huge=advise  Only allocate huge page if requested with madvise(2).

-There is a sysfs file which you can also use to control system wide THP
-configuration for all tmpfs mounts, the file is:
-
-/sys/kernel/mm/transparent_hugepage/shmem_enabled
-
-This sysfs file is placed on top of THP sysfs directory and so is registered
-by THP code. It is however only used to control all tmpfs mounts with one
-single knob. Since it controls all tmpfs mounts it should only be used either
-for emergency or testing purposes. The values you can set for shmem_enabled are:
-
-==  ============================================================
--1  deny: disables huge on shm_mnt and all mounts, for
-    emergency use
--2  force: enables huge on shm_mnt and all mounts, w/o needing
-    option, for testing

+See also Documentation/admin-guide/mm/transhuge.rst, which describes the
+sysfs file /sys/kernel/mm/transparent_hugepage/shmem_enabled: which can
+be used to deny huge pages on all tmpfs mounts in an emergency, or to
+force huge pages on all tmpfs mounts for testing.
 
 tmpfs has a mount option to set the NUMA memory allocation policy for
 all files in that instance (if CONFIG_NUMA is enabled) - which can be
