Subject: [PATCH 00/12] badblocks: bugfix and cleanup for badblocks

From: Zheng Qixing <zhengqixing@...wei.com>

During RAID feature implementation testing, we found several bugs
in badblocks.

This series contains bugfixes and cleanups for MD RAID badblocks
handling code.

Li Nan (8):
  badblocks: Fix error shitf ops
  badblocks: factor out a helper try_adjacent_combine
  badblocks: attempt to merge adjacent badblocks during
    ack_all_badblocks
  badblocks: return error directly when setting badblocks exceeds 512
  badblocks: return error if any badblock set fails
  badblocks: fix the using of MAX_BADBLOCKS
  badblocks: try can_merge_front before overlap_front
  badblocks: fix merge issue when new badblocks align with pre+1

Zheng Qixing (4):
  badblocks: fix missing bad blocks on retry in _badblocks_check()
  badblocks: return boolen from badblocks_set() and badblocks_clear()
  md: improve return types of badblocks handling functions
  badblocks: use sector_t instead of int to avoid truncation of
    badblocks length
