From 3c7759063a7efe1857f8bd5b949e915b18d57f71 Mon Sep 17 00:00:00 2001 From: "Stephen M. Cameron" Date: Thu, 22 Mar 2012 21:40:08 +0100 Subject: [PATCH] cciss: Initialize scsi host max_sectors for tape drive support BugLink: http://bugs.launchpad.net/bugs/987337 commit 395d287526bb60411ff37b19ad9dd38b58ba8732 upstream. The default is too small (1024 blocks), use h->cciss_max_sectors (8192 blocks) Without this change, if you try to set the block size of a tape drive above 512*1024, via "mt -f /dev/st0 setblk nnn" where nnn is greater than 524288, it won't work right.
