The following series implements support for raid0->raid5 migration for IMSM
metadata. These patches also blocks opposite direction of migration.
Code mostly bases on patches sent to you by Adam Kwolek. I have incorporated
your remarks and I tested it quite extensively for comformity with IMSM
standard. I have also removed opposite direction, as it is:
* not standarized yet,
* the design is not settled with you,
* generic grow routines are not compatible with change of chunk size.
Please do not include these patches on 'master' branch, as they are supposed
to be a part of next minor mdadm version (ie. mdadm 3.2.3). I think good place
for them is 'devel-3.2'. Master should be reserved just for bug/stability fixes
for previous release.
