Sender: bugs-owner@FreeBSD.org Precedence: bulk Lots of fixes have been made since that snapshot. The new merged VM/Buffer code is significantly different from the original. It is looking really good now, and I suggest updating to the next snapshot (It might be the release of 2.0.[56]). You should be able to generally mix file and mapped file operations freely now. The msync that used to be needed is gratuitous now. (You still might want to msync for file consistancy reasons). But you should not need to do anything special for programs that mix/match mmap-I/O.
