From 0723d4a8064d52ae44ef2e19749a190b08846be3 Mon Sep 17 00:00:00 2001 From: FUJITA Tomonori Date: Thu, 9 Oct 2008 11:25:42 +0900 Subject: [PATCH] [SCSI] 3w-xxxx: remove unnecessary local_irq_save/restore for scsi sg copy API Since the commit 50bed2e2862a8f3a4f7d683d0d27292e71ef18b9 (sg: disable interrupts inside sg_copy_buffer), no need to disable interrupts before calling scsi_sg_copy_from_buffer. So we can simplify tw_transfer_internal, which disables interrupts just for scsi_sg_copy_from_buffer.
