sync_request_write no longer submits writes to a Faulty device. This has the unfortunate side effect that bitmap bits can be incorrectly cleared if a recovery is interrupted (previously, end_sync_write would have prevented this). This means the next recovery may not copy everything it should, potentially corrupting data. Add a function for doing the proper md_bitmap_end_sync, called from end_sync_write and the Faulty case in sync_request_write. backport note to 4.14: s/md_bitmap_end_sync/bitmap_end_sync Cc: stable@vger.kernel.org 4.14+ Fixes: 0c9d5b12 ("md/raid1: avoid reusing a resync bio after error handling.")
