[PATCH] s390: use normal switch statement for ioctls in dasd_ioctlc
Handle ioctls implemented in dasd_ioctl through the normal switch statement that most drivers use instead of the awkward dasd_ioctl_no_register routine. This avoids searching a linear list on every call to dasd_ioctl(), and allows to give the various ioctl implementation functions sane prototypes, aswell as moving the check for bdev->bd_disk->private_data from the individual functions to dasd_ioctl. (I think it can't actually every be NULL, but let's keep that for later) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
