[PATCH v3 0/4] ext4, jbd2: improve aborting progress

["zhangyi (F)" <yi.zhang@huawei.com>]

Hi,

This series originally aim to fix ext4_handle_error() and ext4_abort()
cannot panic because of we invoke __jbd2_journal_abort_hard() when we
failed to submit commit record without setting JBD2_REC_ERR flag.

I add patch 1 and patch 4 to switch to use jbd2_journal_abort() and do
some cleanup job at this iteration as Jan suggested. I also add patch 3
to fix missing updating ESHUTDOWN problem in commit 818d276ceb8 "ext4:
Add the journal checksum feature", please revirew this series and give
some suggestions.

Changes since v2:
 - Fix spelling mistakes in the first patch.
 - Keep JBD2_REC_ERR and remove the last place that invoke
   jbd2_journal_abort() with 0 errno and the corresponding logic in
   __journal_abort_soft().
 - Fix missing updating errno in the jbd2 sb after jbd2 shutdown abort.

Thanks,
Yi.
