From 2e4c332913b5d39fef686b3964098f0d8fd97ead Mon Sep 17 00:00:00 2001 From: David Miller Date: Tue, 31 Aug 2010 13:35:31 -0700 Subject: [SCSI] sd, sym53c8xx: Remove warnings after vsprintf %pV introducation. GCC warns about empty printf format strings, and after the addition of %pV these existing such cases in the scsi driver layer were exposed enough for the compiler to start seeing them. Based almost entirely upon a patch by Joe Perches. [jejb: fix up sym53c8xx msg] Signed-off-by: David S.

Medium removal should be allowed when the number of open file references drops to 0, not when it becomes non-zero. This patch (as1414) adjusts the test to fix the bug.
