[PATCH 0 of 4] MD RAID10: Improve redundancy of RAID10 'far' and 'offset' algorithms

[Jonathan Brassow <jbrassow@redhat.com>]

Neil,

I've changed the way 'far' and 'offset' algorithms are done to reflect
your latest suggestions.  The case where there were a non-multiple of
'far_copies' devices in the array was the tricky issue we were dealing
with.  I've separated my patch into two - one dealing with the
multiple-of-far_copies case and the other dealing with the non-multiple
case.

I had to make some adjustments to the dm-raid patch that includes the
new 'far' and 'offset' algorithms and I've included that revised patch
in this set.

[PATCH 1 of 4]MD RAID10: Minor non-functional code changes
[PATCH 2 of 4]MD RAID10:  Improve redundancy for 'far' and 'offset' algorithms (part 1)
[PATCH 3 of 4]MD RAID10:  Improve redundancy for 'far' and 'offset' algorithms (part 2)
[PATCH 4 of 4]DM RAID:  Add support for MD's RAID10 "far" and "offset" algorithms

Thanks,
