Darrick J. Wong be20e6c67b md: Call blk_queue_flush() to establish flush/fua support ... Before 2.6.37, the md layer had a mechanism for catching I/Os with the barrier flag set, and translating the barrier into barriers for all the underlying devices. With 2.6.37, I/O barriers have become plain old flushes, and the md code was updated to reflect this. However, one piece was left out -- the md layer does not tell the block layer that it supports flushes or FUA access at all, which results in md silently dropping flush requests. Since the support already seems there, just add this one piece of bookkeeping. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: NeilBrown <neilb@suse.de>		2010-11-24 16:40:33 +11:00
