[PATCH 00/11] xfs: miscellaneous logging, recovery, umount fixes

[Brian Foster]

Hi all,

This series includes a bunch of bug fixes from doing some log recovery
testing. It started with an RFC of the EFI/EFD bits and expanded to
include more fixes as problems were discovered.

Patch 1 removes the superfluous EFI/EFD extent count reference tracking.
Patches 2-6 make a couple cleanups and fix the explicit EFI/EFD
reference counting to avoid leaving EFI items on the AIL in the event of
error. Patches 7-8 fix handling of cancelled icreate transactions in log
recovery. Patch 9 is a repost of a previous log recovery fix. Patches
10-11 fix a couple more mount related crash/hang issues.

Just about all of these problems were reproduced by running repeated
fsstress/godown workloads against XFS. This set has gone ~150 iterations
of said testing before hitting some kind of recovery time directory
corruption in the form of a dir. block write verifier failure. I'll see
if it is reproducible, but I don't think it's related to anything
here since I haven't touched directory code...
