Subject: [PATCH] getinfo_super1: when deciding whether the array is clean or
dirty, compare sb->resync_offset against MaxSector and not
against sb->size
With RAID6 resyncing and subsequent drive failures, it is possible to
reach the case, in which sb->resync_offset==sb->size. This happens
when resync is aborted due to drive failures, a
