Btw, Smatch doesn't like that file at all...
sock->file = sock_alloc_file(sock, O_NONBLOCK, NULL);
^^^^ ^^^^
sock_alloc_file() calls release_sock() on error but the left hand
side of the assignment dereferences "sock". This isn't the bug and I
didn't report this earlier because there is an assert that it doesn't
fail.
