In the case of TCP and UDP, further per-connection state is 137*199767f8SToomas Soome * hung off of inp_ppcb most of the time. Almost all fields of struct inpcb 138*199767f8SToomas Soome * are static after creation or protected by a per-inpcb rwlock, inp_lock.

For these fields, all of the listed locks must be write-locked for 141*199767f8SToomas Soome * any modifications. However, these fields can be safely read while any one of 142*199767f8SToomas Soome * the listed locks are read-locked.
