Subject: [PATCH] Grow: Do not try to restart if reshape is running
Grow process did not check if reshape is already started
when deciding about restarting.
Sync_action should be checked in this case, and if
reshape is running - restart flag should not be set.
Otherwise, Grow process will fail to write data to
sysfs, and reshape will not be continued.

Subject: [PATCH] IMSM: Add warning message when assemble spanned container
Due to several changes in code assemble with disks
spanned between different controllers can be obtained
in some cases. After IMSM container will be assembled, check HBA of
disks, and print proper warning if mismatch is detected.
