Hi:
This patch set is the third version which want to fix a data corruption,
have been testd by xfstests.
- The first patch fix the data corruption problem we captured. The root
case is that we forgot to clear dirty flag when revorking a buffer
belongs to older transaction.
- The second and third patches are cleanup patches which remove
clean_bdev_aliases() related calls and move the logic to
jbd2_journal_forget() when forgetting metadata (suggested by Jan Kara).
- The last patch change the return value of ext4_ext_convert_to_initialized().
Please review.
Thanks,
Yi.
----------
Changes since v2:
- Change the commit log and comments in the first patch.
- Add the three cleanup patches to remove all clean_bdev_aliases() calls
