Pull xfs fixes from Darrick Wong:
 "Here are a few fixes for some corruption bugs and uninitialized
  variable problems. The few patches here have gone through a few days
  worth of fstest runs with no new problems observed.

  Changes since last update:

   - Fix a bunch of static checker complaints about uninitialized
     variables and insufficient range checks.

   - Avoid a crash when incore extent map data are corrupt.

   - Disallow FITRIM when we haven't recovered the log and know the
     metadata are stale.

   - Fix a data corruption when doing unaligned overlapping dio writes"
