From: Zhang Yi <yi.zhang@xxxxxxxxxx> 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.
