tcp_write_space
Hi,
Why isn't the sk->callback_lock aquired in the tcp_write_space callback ??
Is this intentional ?

Yes, this lock is not required in this case because tcp_write_space() is called only from under socket lock, which is stronger than callback_lock. This is true _only_ for TCP sockets.
