From 4e7c6816d680d1945916db047a47847afe4b9b02 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 31 May 2005 17:47:36 +0200 Subject: [PATCH] [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 [ 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 --- drivers/ide/ide-cd.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/ide/ide-cd.c b/drivers/ide/ide-cd.c index 78e3e7b24d..39f3e9101e 100644 --- a/drivers/ide/ide-cd.c +++ b/drivers/ide/ide-cd.c @@ -1936,7 +1936,7 @@ static ide_startstop_t cdrom_do_block_pc(ide_drive_t *drive, struct request *rq) * NOTE!
