Merge tag 'md/3.20' of git://neil.brown.name/md
Pull md updates from Neil Brown:
- assorted locking changes so that access to /proc/mdstat
and much of /sys/block/mdXX/md/* is protected by a spinlock
rather than a mutex and will never block indefinitely.
- Make an 'if' condition in RAID5 - which has been implicated
in recent bugs - more readable.
- misc minor fixes
