Regarding sock_readers - TCP bh should always lock_sock before
doing anything with a socket, with the only exception of one
dubious case in tcp_v[46]_err(). Do you know of more?
Not entirely true. Main tcp receive path only checks to make sure
readers is zero, then it moves on. This is why lock_sock() performs a
synchronize_bh() as part of it's implementation, on SMP this matters.
Don't spread FUD without checking the code please :-)
