  ext4: fix potential null pointer dereference in ext4_free_inode (2014-07-12 16:11:42 -0400)

----------------------------------------------------------------
More bug fixes for ext4 -- most importantly, a fix for a bug
(introduced in 3.15) that can end up triggering a file system
corruption error after a journal replay.  (It shouldn't lead to any
actual data corruption, but it is scary and can force file systems to
be remounted read-only, etc.)

----------------------------------------------------------------
Eric Sandeen (1):
      ext4: disable synchronous transaction batching if max_batch_time==0

Namjae Jeon (1):
      ext4: fix potential null pointer dereference in ext4_free_inode

Theodore Ts'o (5):
      ext4: fix unjournalled bg descriptor while initializing inode bitmap
      ext4: clarify error count warning messages
      ext4: clarify ext4_error message in ext4_mb_generate_buddy_error()
      ext4: revert commit which was causing fs corruption after journal replays
      ext4: fix a potential deadlock in __ext4_es_shrink()
