Modified files:
sys/kern uipc_usrreq.c
Log:
Reduce periods of simultaneous acquisition of various socket buffer
locks and the unplock during uipc_rcvd() and uipc_send() by caching
certain values from one structure while its locks are held, and
applying them to a second structure while its locks are held. If
done carefully, this should be correct, and will reduce the amount
of work done with the global unp lock held.
