[md PATCH 00/26] Pending md patches.

[NeilBrown <neilb@suse.de>]

I probably don't post my pending patches as often as I
should ... I think I got out of the habit somewhere there.
So I'll try to do better.

Following are a collection of patches that I hope to submit
for 3.20.  There is lots of clean-up and some re-arranging
of locking to make sure that accesses to /proc/mdstat and
most accesses to sysfs files never block.

Review and testing most welcome.

All of these are in my "for-next" branch, and so are in
linux-next.

Thanks,
NeilBrown
