2008-01-28	blktrace: Add blktrace ioctls to SCSI generic devices	Christof Schmitt	1	-1/+4
	Since the SCSI layer uses the request queues from the block layer, blktrace can also be used to trace the requests to all SCSI devices (like SCSI tape drives), not only disks. The only missing part is the ioctl interface to start and stop tracing. This patch adds the SETUP, START, STOP and TEARDOWN ioctls from blktrace to the sg device files. With this change, blktrace can be used for SCSI devices like for disks, e.g.: blktrace -d /dev/sg1 -o - \| blkparse -i - Signed-off-by: Christof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-29	compat_ioctl: fix block device compat ioctl regression	Philip Langdale	1	-1/+1
	The conversion of handlers to compat_blkdev_ioctl accidentally disabled handling of most ioctl numbers on block devices because of a typo. Fix the one line to enable it all again. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <axboe@carl.home.kernel.dk>
2007-10-10	compat_ioctl: move floppy handlers to block/compat_ioctl.c	Arnd Bergmann	1	-0/+336
	The floppy ioctls are used by multiple drivers, so they should be handled in a shared location. Also, add minor cleanups. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-10	compat_ioctl: move cdrom handlers to block/compat_ioctl.c	Arnd Bergmann	1	-0/+83
	These are shared by all cd-rom drivers and should have common handlers. Do slight cosmetic cleanups in the process. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-10	compat_ioctl: move BLKPG handling to block/compat_ioctl.c	Arnd Bergmann	1	-0/+31
	BLKPG is common to all block devices, so it should be handled by common code. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-10	compat_ioctl: move hdio calls to block/compat_ioctl.c	Arnd Bergmann	1	-0/+70
	These are common to multiple block drivers, so they should be handled by the block layer. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-10	compat_ioctl: handle blk_trace ioctls	Arnd Bergmann	1	-0/+54
	blk_trace_setup is broken on x86_64 compat systems, this makes the code work correctly on all 64 bit architectures in compat mode. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-10	compat_ioctl: add compat_blkdev_driver_ioctl()	Arnd Bergmann	1	-1/+120
	Handle those blockdev ioctl calls that are compatible directly from the compat_blkdev_ioctl() function, instead of having to go through the compat_ioctl hash lookup. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-10	compat_ioctl: move common block ioctls to compat_blkdev_ioctl	Arnd Bergmann	1	-0/+121
	Make compat_blkdev_ioctl and blkdev_ioctl reflect the respective native versions. This is somewhat more efficient and makes it easier to keep the two in sync. Also get rid of the bogus handling for broken_blkgetsize and the duplicate entry for BLKRASET. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
