From 67768f675ffa587d6081ed1d259e796823023926 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Mon, 25 Feb 2008 14:23:45 +0100 Subject: [PATCH] [SCSI] ps3rom: fix wrong resid calculation bug sg driver rounds up the length in struct scatterlist to be a multiple of 512 in some conditions. So LLDs can't use the data length in a sg list to calculate residual. Instead, the length in struct scsi_cmnd should be used.
