[PATCH v2 0/4] buffered write and indlen fixes

[Brian Foster <bfoster@redhat.com>]

Hi all,

This is v2 of the indlen split fixup series. The indlen patches are
mostly the same except for changes to use do_div() rather than built-in
division, which causes problems on 32-bit arches.

Patches 1-2 are new and facilitate testing. Patch 1 fixes a couple
issues in buffered write failure handling that I ran into. Patch 2
reintroduces the "fail writes" mechanism as a "drop writes" mechanism to
re-enable the ability to test the indlen code from userspace. I will
follow up with xfstests patches shortly that use this mechanism to
reproduce both issues fixed by patches 3 and 4. Thoughts, reviews,
flames appreciated.

Brian

v2:
- Use do_div() to fix 32-bit builds.
- Prepend patches 1-2 to re-enable indlen testing from xfstests.
v1: http://www.spinics.net/lists/linux-xfs/msg04083.html

Brian Foster (4):
  xfs: clear delalloc and cache on buffered write failure
  xfs: resurrect debug mode drop buffered writes mechanism
  xfs: handle indlen shortage on delalloc extent merge
  xfs: split indlen reservations fairly when under reserved
