From 786231af0a4ac6d78cef51fa7e9c3dd63f016195 Mon Sep 17 00:00:00 2001 From: Kai Makisara Date: Fri, 11 Jul 2008 15:06:40 +0300 Subject: [SCSI] st: Remove bogus memset MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mike Christie noticed a bogus memset. It can be removed as dead code since the number of bytes in the driver buffer in fixed block mode is always a multiple of the tape block size.
