From daef265f1590cf3e6de989d074041a280c82d58b Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 10 Jan 2006 10:48:02 +0100 Subject: [PATCH] dm: don't enable bouncing by default DM doesn't need to bounce bio's on its own, but the block layer defaults to that in blk_queue_make_request(). The lower level drivers should bounce ios themselves, that is what they need to do if not layered below dm anyways.
