Moreover, if it was NULL we would have crashed anyway when jumping to 'out' and trying to unlock the sock. Furthermore, if we had assigned a different value to 'sk' we would have been calling lock_sock() and release_sock() on different sockets. My conclusion is that these two lines are complete nonsense and only serve to confuse the reader. Signed-off-by: Vegard Nossum Signed-off-by: David S.
