It survived my overnight test, which I find quite amazing considering
what I just ripped out and replaced! In fact, the patch is running
better then HEAD is.
I did notice that it does not pick up on NFS server-side file changes.
If the DFly client running this patch has a negative cache entry for
a file, and the file is created by the server, the DFly client doesn't
pick up on it. Even unmounting and remounting doesn't work, so my
unmount-time cache purge isn't working. I have some cache invalidation
work to do :-)
I am going to fix VOP_CLOSE and fix the cache timeouts and unmount-time
invalidation issues and come up with another patch set. If that one works
I'll commit it to HEAD and move on to the next step.
