Hi:

This patch set is the forth version that want to fix a data corruption
problem. I have already fix all review comments from Jan Kara and tested
by xfstests.

Thanks,
Yi.

----------

Changes since v3:
 - Make the comment more readable in the first two patches.
 - Remove the unneeded __jbd2_journal_temp_unlink_buffer calls.
 - Add the Reviewed-by signature.

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().

zhangyi (F) (4):
  jbd2: make sure dirty flag is cleared while revorking a buffer which
    belongs to older transaction
  jbd2: discard dirty data when forgetting an un-journalled buffer
  ext4: cleanup clean_bdev_aliases() calls
  ext4: convert ext4_split_extent() to return requested length
