Hi,
The following are a series of patches for 2.6.32-rc that I hope to
ask Linus to pull mid next week. They are already in my for-next tree.
Review always welcome.
Dan, I would particularly like you to check over
raid6/async_tx: handle holes in block list in async_syndrome_val
md/async: don't pass a memory pointer as a page pointer.
as they fix some issues with the recent conversion of raid6 to work
with async offload. Problems particularly occurred with 'ddf' style
layouts where there the Q syndrome is calculated over data blocks and
some 'zero' blocks.
My mdadm test suite now has some tests that test every single RAID5
and RAID6 layout and every combination of devices failing. And also
uses the new reshape functionality to transition an array through
each different layout. It has been very helpful at finding bugs.
One particularly important bug is that thought 2.6.31 can reshape a
RAID5 to have fewer devices, if the reshape is aborted in the middle,
2.6.31 cannot restart that reshape. With these patches 2.6.32 will
be able to. I suspect that when I release mdadm-3.1 it will refuse
to reduce the number of devices on kernels earlier than 2.6.32.
Thanks,
NeilBrown
