Hi,
thanks for replying.
After __tcp_close(),I keep calling __tcp_poll() until
state is _CLOSED. But it seems endless,even setup
reuse option to 1sec in sock,the state is still
TIME_WAIT..,
Have you met this situation before?
Could force to destory the state to _CLOSED?
If so,is there any potential problem?
thank you
Sam
