poll() call may be locked by concurrent reading from the same stream
socket.

Fine, the fix is technically correct since we own u->readlock mutex,
another thread cannot consume the just requeued skb. 

Small note : the words "locking" and "locked" are more used to describe
the action of taking a spinlock/mutex/rwlock or something, while the bug
you fixed is more about poll() system call being blocked/frozen forever.

Thanks !

Applied, with 'lock{ing,ed}' adjusted to 'block{ing,ed}'.
