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
