PULL REQUEST: md patches for 2.6.30 merge window
From: Neil Brown
Date: Thu Apr 02 2009 - 19:52:23 EST
Hi Linus,
please pull my md development tree as described below.
Highlights (for me) are:
moving .h file from include/linux to driver/md from Christoph.
I'm already loving the fact that e.g. raid5.h is in the same
directory as raid5.c :-)
more options for reshaping arrays including raid5->raid6 and back,
reducing the number of drives in an array and changing the chunksize.
There is lots of other stuff, bug fixes and other feature
enhancements.
A small change to md/Makefile touches 'dm' as well, hence Cc to
Alasdair.
Thanks,
NeilBrown
