From 15fa6e81650a167f82dc0d478f290f1cffa9183d Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 18 Jun 2010 12:10:18 +0200 Subject: virtio_blk: add default case to cmd type switch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit On compilation, gcc correctly detects that we do not handle all types: In function ‘blk_done’: warning: enumeration value ‘REQ_TYPE_FS’ not handled in switch warning: enumeration value ‘REQ_TYPE_SENSE’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_SUSPEND’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_RESUME’ not handled in switch warning: enumeration value ‘REQ_TYPE_PM_SHUTDOWN’ not handled in switch warning: enumeration value ‘REQ_TYPE_LINUX_BLOCK’ not handled in switch warning: enumeration value ‘REQ_TYPE_ATA_TASKFILE’ not handled in switch warning: enumeration value ‘REQ_TYPE_ATA_PC’ not handled in switch which is a bit pointless since this is at the end of the request processessing. Add a default case that just breaks out.
