Pull MD updates from Shaohua Li: "A few fixes of MD for this merge window. Mostly bug fixes: - raid5 stripe batch fix from Amy - Read error handling for raid1 FailFast device from Gioh - raid10 recovery NULL pointer dereference fix from Guoqing - Support write hint for raid5 stripe cache from Mariusz - Fixes for device hot add/remove from Neil and Yufen - Improve flush bio scalability from Xiao" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md: MD: fix lock contention for flush bios md/raid5: Assigning NULL to sh->batch_head before testing bit R5_Overlap of a stripe md/raid1: add error handling of read error from FailFast device md: fix NULL dereference of mddev->pers in remove_and_add_spares() raid5: copy write hint from origin bio to stripe md: fix two problems with setting the "re-add" device state. raid10: check bio in r10buf_pool_free to void NULL pointer dereference md: fix an error code format and remove unsed bio_sector
