Subject: [PATCH 0/3] jbd2: some fixes and cleanup about "jbd2: fix several checkpoint inconsistent issues"

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

These patch set includes 2 fixes and 1 cleanup about "jbd2: fix several
checkpoint inconsistent issues" patch set[1] recently applied in dev
branch. The first patch fix a performance regression introduced while
merging journal_shrink_one_cp_list(). The second one add a missing
check before dropping checkpoint buffer that could lead to filesystem
inconsistent. The last patch which is from Yang Li, remove the unused
__cp_buffer_busy() helper. Please see the corresponding patch for
details.
