Subject: [PATCH v3 0/4] ext4: fix a data corruption problem

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
   and change the return value of ext4_ext_convert_to_initialized().
