Pull ext4 fixes from Ted Ts'o: "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." * tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4: ext4: Avoid underflow in ext4_trim_fs() ext4: Checksum the block bitmap properly with bigalloc enabled ext4: fix undefined bit shift result in ext4_fill_flex_info ext4: fix metadata checksum calculation for the superblock ext4: race-condition protection for ext4_convert_unwritten_extents_endio ext4: serialize fallocate with ext4_convert_unwritten_extents
