spin_lock question

["Ming Chen" <tomingchen@xxxxxxxxx>]

I've a kernel loadable module (KLM) running under 2.6 kernel. The module will insert a new TCP connection to a queue and delete it when connection is torn down.

Do I have to do spin_lock to guard critical section ? I think since the bottom half driver feed packet to my module one-by-one, so I think I don't have to do spin_lock.

Could someone give comments ?

Thanks,
Ming
