From dc8875e1078961591af4fbf9556c44648bf28d11 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Thu, 15 Nov 2007 15:42:30 -0800 Subject: [SCSI] docbook and kernel-doc updates - Change title to remove "Mid-Layer" since the doc is about all of the SCSI layers. - Use "SCSI" instead of "scsi" in docbook text. - Use "*/" to end kernel-doc notation blocks. - A few other minor typo fixes.
