From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Nicholas A. Bellinger" Subject: [PATCH 2/2] scsi_debug: Add XDWRITEREAD_32 support Date: Tue, 21 Sep 2010 22:50:56 -0700 Message-ID: <1285134656-7764-1-git-send-email-nab@linux-iscsi.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-scsi , linux-kernel Cc: James Bottomley , Douglas Gilbert , FUJITA Tomonori , Boaz Harrosh , Nicholas Bellinger List-Id: linux-scsi@vger.kernel.org From: Nicholas Bellinger This patch adds XDWRITEREAD_32 support to scsi_debug.c in scsi_debug_queuecommand(). It follows the other READ_32 and WRITE_32 emulation for VARIABLE_LENGTH_CMD, and adds a simple goto back to existing XDWRITEREAD_10 processing logic which already properly supports 64-bit LBA and 32-bit transfer length in get_data_transfer_info() Signed-off-by: Nicholas A.
