Merge tag 'md/4.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md
Pull MD fixes from Shaohua Li: - Several bug fixes for raid5-cache from Song Liu, mainly handle journal disk error - Fix bad block handling in choosing raid1 disk from Tomasz Majchrzak - Simplify external metadata array sysfs handling from Artur Paszkiewicz - Optimize raid0 discard handling from me, now raid0 will dispatch large discard IO directly to underlayer disks. * tag 'md/4.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md: raid1: prefer disk without bad blocks md/r5cache: handle sync with data in write back cache md/r5cache: gracefully handle journal device errors for writeback mode md/raid1/10: avoid unnecessary locking md/raid5-cache: in r5l_do_submit_io(), submit io->split_bio first md/md0: optimize raid0 discard handling md: don't return -EAGAIN in md_allow_write for external metadata arrays md/raid5: make use of spin_lock_irq over local_irq_disable + spin_lock
