Hi all,
I thought it was time I posted my patch queue for review to be sure
it would be ready for the next merge window.
Apart from sundry bug fixes and minor improvements there are two big
themes here
1/ enhancements to level conversion so e.g. we can now convert RAID0
to RAID5 or RAID10 (near-2 only) and back.
2/ general refactoring of bits of md code - some functions
(e.g. do_md_stop) had become really big and were just a mess of
stuff that all had to be done at much the same time. It is now
broken into somewhat meaningful parts. There is a deeper reason
for doing this refactoring .... you'll find out soon. :-)
This is all available at
git://neil.brown.name/md for-next
and should be in linux-next in a day or two.
All review, testing, and comments most welcome.
Unfortunately it doesn't contain a fix for
https://bugzilla.kernel.org/show_bug.cgi?id=15464
I stared at that for some time and haven't made any headway.
