|| ||[PATCH 00/18] Assorted md patches headed for 2.6.30|

|| ||Article, Thread
following is my current patch queue for 2.6.30, in case anyone would
like to review or otherwise comment.
They should show up in -next shortly.
Probably the most interesting are the last few which provide support
for converting a raid1 into a raid5, and a raid5 into a raid6.
I plan to do some more work here so the code might change a bit before
final submission, as I work out how best ot factor the code.
mdadm doesn't current support these conversions, but you can
echo raid5 > /sys/block/md0/md/level
to change a 2-drive raid1 into a raid5. Similarly for 5->6
The raid6 array created will have a somewhat unusual layout in that
all the Q blocks will be on the last drive. Later I'll create
functionality to restripe the array so that the Q block is rotated
around all the drives as you would expect.
Comments and testing very welcome.
