Really ?
Again, TCP stack locks the socket most of the time.
The fact that lockdep does not understand this is not a reason to add
this overhead.
I don't see how lockdep does not understand this? I think I added the
appropriate helper to exactly verify if we have the socket lock with
lockdep, please have a look at lockdep_sock_is_held in patch #2.
Some of the patches also just reorder the rcu_read_lock, which is anyway
mostly free.
Bye,
Hannes
