From 999dec57f6c7d75176f981d4b5e4df8c30c1c723 Mon Sep 17 00:00:00 2001 From: aliguori Date: Sun, 29 Mar 2009 01:31:48 +0000 Subject: [PATCH] remove dead code in bdrv_check_request (Christoph Hellwig) Remove code dealing with negative sector numbers for byte access in bdrv_check_request as sector numbers can't ever be negative. Previously we supported negative sector counts for byte access, but never sector numbers.
