Heinz Mauelshagen affa9d28f7 dm raid: don't allow "write behind" with raid4/5/6 ... Remove CTR_FLAG_MAX_WRITE_BEHIND from raid4/5/6's valid ctr flags. Only the md raid1 personality supports setting a maximum number of "write behind" write IOs on any legs set to "write mostly". "write mostly" enhances throughput with slow links/disks. Technically the "write behind" value is a write intent bitmap property only being respected by the raid1 personality. It allows a maximum number of "write behind" writes to any "write mostly" raid1 mirror legs to be delayed and avoids reads from such legs. No other MD personalities supported via dm-raid make use of "write behind", thus setting this property is superfluous; it wouldn't cause harm but it is correct to reject it.
