Subject: [PATCH v2 0/6] jbd2: fix several checkpoint inconsistent issues

From: Zhang Yi <yi.zhang@...wei.com>

v1->v2:
 - Drop the last patch in [1].
 - Merge journal_clean_one_cp_list() into journal_shrink_one_cp_list().
 - Fix the race issues through trying to hold buffer lock and check
   dirty state under the lock.
 - Append a cleanup patch, remove __journal_try_to_free_buffer().

Hello,

The first two patches are from [1] and are not changed, appending
another four (it depends on the first three) to fix another three race
issues in the checkpoint procedure which could also lead to inconsistent
results.

Thanks,
Yi.
