*	[PATCH] blktrace: only add a bounce trace when we really bounce	Jens Axboe	2007-01-12	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \|	Currently we issue a bounce trace when __blk_queue_bounce() is called, but that merely means that the device has a lower dma mask than the higher pages in the system. The bio itself may still be lower pages. So move the bounce trace into __blk_queue_bounce(), when we know there will actually be page bouncing.

*	[PATCH] BLOCK: Separate the bounce buffering code from the highmem code [try #6]	David Howells	2006-09-30	1	-0/+302
	Move the bounce buffer code from mm/highmem.c to mm/bounce.c so that it can be more easily disabled when the block layer is disabled. !!!NOTE!!! There may be a bug in this code: Should init_emergency_pool() be contingent on CONFIG_HIGHMEM? Signed-Off-By: David Howells <dhowells@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
