Module Name:    src
Committed By:   martin
Date:           Mon Mar 22 16:49:41 UTC 2010

Modified Files:
        src/sys/dev/scsipi: cd.c
        src/sys/sys: dkio.h

Log Message:
Add a DIOCTUR (test unit ready) ioctl, to allow userland to easily
(and silently) check for presence of media. While this would be easy
to implement via SCIOCCOMMAND, our kernel has quirks for this
command, which otherwise would not be readily available to userland
applications.
