The following series implements support for array degradation during reshape.
Series mostly fixes problems in handling degradation during reshape
in imsm metadata .
Main common problem that last patch resolves is is lack of BBM support.
md on disk failure reports BBM event to user space and waits for an answer.
The side effect of this action is stopping reshape process. The last patch
/together with md patch sent separately/ allows for disabling BBM mechanism.
This is similar as native metadata v0.9 works.
