Subject: [PATCH 3.16 71/99] jbd2: switch to use jbd2_journal_abort() when
 failed to submit the commit record

3.16.84-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: "zhangyi (F)" <yi.zhang@...wei.com>

commit d0a186e0d3e7ac05cc77da7c157dae5aa59f95d9 upstream.

We invoke jbd2_journal_abort() to abort the journal and record errno
in the jbd2 superblock when committing journal transaction besides the
failure on submitting the commit record. But there is no need for the
case and we can also invoke jbd2_journal_abort() instead of
__jbd2_journal_abort_hard().
