  ext4: Avoid underflow in ext4_trim_fs() (2012-10-22 18:01:19 -0400)

----------------------------------------------------------------
Various bug fixes for ext4.  The most serious of them fixes a security
bug (CVE-2012-4508) which leads to stale data exposure when we have
fallocate racing against writes to files undergoing delayed
allocation.  We also have two fixes for the metadata checksum feature,
the most serious of which can cause the superblock to have a invalid
checksum after a power failure.

----------------------------------------------------------------
Dmitry Monakhov (2):
      ext4: serialize fallocate with ext4_convert_unwritten_extents
      ext4: race-condition protection for ext4_convert_unwritten_extents_endio

Lukas Czerner (2):
      ext4: fix undefined bit shift result in ext4_fill_flex_info
      ext4: Avoid underflow in ext4_trim_fs()

Tao Ma (1):
      ext4: Checksum the block bitmap properly with bigalloc enabled

Theodore Ts'o (1):
      ext4: fix metadata checksum calculation for the superblock
