From beb2fdcad14af14fa38d5098003bd0f53e1c1185 Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Thu, 25 Jan 2007 22:35:47 +0100 Subject: ieee1394: sbp2: lower block queue alignment requirement The old setting is copy & waste from usb-storage and doesn't apply to sbp2. There is only 4-byte alignment required for everything, except for S/G table elements which have to be 8-byte aligned according to the SBP-2 spec. (They happen to be ____cacheline_aligned in our implementation. Whether that's good is another question.) We now simply don't tune block queue alignment at all. The default alignment would surely never become anything else than a multiple of 4, else tons of calls to blk_queue_dma_alignment would have to be added everywhere in drivers/...
