V2 changes:
1. move md_p.h from the second patch to the first one to fix compile issues.
2. remove unnecessary code in patch 2 and 3.
Hi,
This series aim to change the capacity for clustered raid10
just like normal raid10.
The first patch ensure all nodes have the same bitmap size
before reshape. After that, master node broadcasts RESYNCING
msg in reshape_request and slave nodes update reshape_position,
this is achieved by the second patch.
The 3rd patch addes sanity check for resync_info_get, and
other patches are introduced to handle different kinds of
cases which happened during grow clustered raid10. And the
last patch cleans up suspend_info which is not necessary.
Thanks,
Guoqing
