[PATCH] BLOCK: Move the ReiserFS device ioctl compat stuff to the ReiserFS driver [try #6]
Move the ReiserFS device ioctl compat stuff from fs/compat_ioctl.c to the ReiserFS driver so that the ReiserFS header file doesn't need to be included. Signed-Off-By: David Howells <dhowells@redhat.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
