From 0da2f50944976e890ccc9436ab88c0da87788d02 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 3 Sep 2010 11:56:16 +0200 Subject: ide: remove unnecessary blk_queue_flushing() test in do_ide_request() Unplugging from a request function doesn't really help much (it's already in the request_fn) and soon block layer will be updated to mix barrier sequence with other commands, so there's no need to treat queue flushing any differently. ide was the only user of blk_queue_flushing(). Remove it. Signed-off-by: Tejun Heo Cc: Christoph Hellwig Acked-by: David S.
