[md PATCH 00/16] md patches for 2.6.40

[NeilBrown <neilb@suse.de>]

I'm slowly working through getting bad-block-logs working, but it
looks like it won't be ready for 2.6.40 (so many distractions.... and
the code is rather complex and hard to test).

However while doing that coding I found several opportunities to clean
up existing code and various bug reports have come in that need
addressing.

So here are that patches that I currently plan to submit for 2.6.40.
They are all in my for-next branch so should appear in -next shortly.

As always, any review is most welcome.

Thanks,
NeilBrown
