I have a couple of other reviews and hopefully some more testing coming in, and will commit in a few days if all continues to go well. An updated version of the patch is here: http://www.watson.org/~robert/freebsd/netperf/20080811-7stable-rwlock-inpcb.diff There are no changes from previous versions, but I was asked to regenerate the patch with function names, so have done so. Anyone out there running name servers, NFS over UDP, and other UDP workloads: your testing of this patch prior to commit would be much appreciated.
