[PATCH] unify sys_ptrace prototype
Make sure we always return, as all syscalls should. Also move the common prototype to <linux/syscalls.h> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Miklos Szeredi <miklos@szeredi.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
