Jan Chaloupka f7282b7bbf madvise.2: Starting with Linux 3.5, more file systems support MADV_REMOVE 
As from upstream commit:

commit 3f31d07571eeea18a7d34db9af21d2285b807a17
Author: Hugh Dickins <hughd@google.com>
Date:   Tue May 29 15:06:40 2012 -0700

     mm/fs: route MADV_REMOVE to FALLOC_FL_PUNCH_HOLE

     Now tmpfs supports hole-punching via fallocate(), switch madvise_remove()
     to use do_fallocate() instead of vmtruncate_range(): which extends
     madvise(,,MADV_REMOVE) support from tmpfs to ext4, ocfs2 and xfs.

madvise(,,MADV_REMOVE) support was extended by ext4, ocfs2 and xfs.

bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1120294

Justification from Rafael Aquini:
Well, that code is committed in kernel since v3.5 (2012) and it
surely is the expected behaviour since. It seems to me that
madvise(2) man page text for MADV_REMOVE just got out-of-date in
that regard.

This patch mentions this support in madvise.2 man page.

Reworded and corrected by Michael Kerrisk and Hugh Dickins. Thank you.

Michael Kerrisk 845c8bea2d madvise.2: Recast discussion of 'advice' into two groups of values 
madvise() is one of those system calls that has congealed over
time, as has the man page. It's helpful to split the discussion
of 'advice' into those flags into two groups:

* Those flags that are (1) widespread across implementations;
  (2) have counterparts in posix_madvise(3); and (3) were present
  in the initial Linux madvise implementation.
* The rest, which are values that (1) may not have counterparts
  in other implementations; (2) have no counterparts in
  posix_madvise(3); and (3) were added to Linux in more recent
  times.
