[PATCH] md: Don't clear bits in bitmap when writing to one device fails during recovery
Currently a device failure during recovery leaves bits set in the bitmap.
This normally isn't a problem as the offending device will be rejected because
of errors. However if device re-adding is being used with non-persistent
bitmaps, this can be a problem.
