This version of the bigalloc patch set has a bunch of fixes so that
delayed allocation and i_blocks/quota works correctly, which was the
major set of failures that we had been seeing. There is still are a few
warnings triggering in ext4_da_reserve_space():
EXT4-fs (sdb2): ext4_da_update_reserve_space: ino 13, used 1 with only 0 reserved data
caused by fsstress, but this should be much more stable. Thanks to
Aditya Kali for his yeoman work to fix this problem.
The next branch in e2fsprogs branch also has a number of bigalloc fixes.
E2fsck should now be able to properly check bigalloc file systems, and
repair many of the more common bigalloc file system corruption issues.
