Subject: [PATCH v2 0/5] jbd2: Add errseq to detect writeback

According to discussions in [1], this patchset adds errseq in journal to
enable JDB2 detecting meatadata writeback error of fs dev. Then, orginal
checking mechanism could be removed.

v1->v2:
  Fix some misspelling words.
  Patch 1: "fallen on" -> "written to"
  Patch 4: "can detects" -> "can detect"

Zhihao Cheng (5):
  jbd2: Add errseq to detect client fs's bdev writeback error
  jbd2: Replace journal state flag by checking errseq
  jbd2: Remove unused 'JBD2_CHECKPOINT_IO_ERROR' and 'j_atomic_flags'
  jbd2: Abort journal when detecting metadata writeback error of fs dev
  ext4: Move ext4_check_bdev_write_error() into nojournal mode
