Hi,
Please pull MD update for 4.12-rc2. This update mainly fixes bugs:
- 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.
Thanks,
Shaohua
