Several failure\npaths in raid10_write_request() complete the bio and return without\nreaching the normal write completion path, causing the corresponding\nmd_write_end() to be skipped.\n\nMake raid10_write_request() return a status indicating whether the write\nrequest was successfully queued. This allows raid10_make_request() to\nrelease the writes_pending reference with md_write_end() when a write\nrequest fails."
