[PATCH] Relax idecd dma alignment check
Only the address needs alignment of mask bits, length should work with a relaxed alignment check. Signed-off-by: Jens Axboe <axboe@suse.de> [ This is take 2: make the length check be for 16-byte alignment, not just word alignment. That should hopefully keep everybody happy, while still allowing CD writing with DMA ] Signed-off-by: Linus Torvalds <torvalds@osdl.org>
