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: NChristof Schmitt <christof.schmitt@de.ibm.com> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

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: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NJens Axboe <axboe@carl.home.kernel.dk>

The floppy ioctls are used by multiple drivers, so they should be handled in a shared location. Also, add minor cleanups. Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

These are shared by all cd-rom drivers and should have common handlers. Do slight cosmetic cleanups in the process. Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

BLKPG is common to all block devices, so it should be handled by common code. Signed-off-by: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

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: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

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: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>

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: NArnd Bergmann <arnd@arndb.de> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>
