Rather than hacking a fix, I finally decided to rework the code correctly. If I don't have a good fix by tonight (say, 21:00 EST) I'll back out my changes -- and we will have a proper fix within a few days. I don't want to hold up other's progress much longer. The management of the vnodes and VM interface, and associated reference counts is pretty tricky (and currently wrong.) PHK is working on the general vnode and namecache management (which is intricate in it's own right), but I am working the VM interface and making it fine grained SMP friendly. Currently, it isn't. -- John dyson@freebsd.org jdyson@nc.com
