Merge tag 'md-3.11' of git://neil.brown.name/md
Pull md updates from NeilBrown:
"Mostly fixes, with a few minor features (eg 'last_sync_action' sysfs
file)
A couple marked for -stable including one recent bug which causes a
RAID10 reshape to complete without moving any data :-(
A couple more bugfixes (at least) to come, but haven't confirmed the
right solution yet."
