Changes in this revision address the minor comment and function name
issues brought up by Naoya Horiguchi.  Patch set is also rebased on
current "mmotm/since-4.1".  This revision does not introduce any
functional changes.

As suggested during the RFC process, tests have been proposed to
libhugetlbfs as described at:
http://librelist.com/browser//libhugetlbfs/2015/6/25/patch-tests-add-tests-for-fallocate-system-call/
fallocate(2) man page modifications are also necessary to specify
that fallocate for hugetlbfs only operates on whole pages.  This
change will be submitted once the code has stabilized and been
proposed for merging.

hugetlbfs is used today by applications that want a high degree of
control over huge page usage.  Often, large hugetlbfs files are used
to map a large number huge pages into the application processes.
The applications know when page ranges within these large files will
no longer be used, and ideally would like to release them back to
the subpool or global pools for other uses.  The fallocate() system
call provides an interface for preallocation and hole punching within
files.  This patch set adds fallocate functionality to hugetlbfs.

v4:
  Renamed vma_abort_reservation() to vma_end_reservation().

...

v3 patch series:
Reviewed-by: Naoya Horiguchi <redacted>
Acked-by: Hillf Danton <redacted>

eek.  Please don't hide the reviews and acks in [0/n] like this.  I
don't expect to see them there, which causes me to park the patch
series until I'm feeling awake enough to undertake the patchset's first
ever review.
