Subject: Has anyone run the Connectathon Testsuite recently?

I checked out kernel 2.4.9-6 from RedHat 7.1 updates. It failed the
Connectathon Testsuite against the Linux and none-Linux server. I
believe both NFS server and client are broken in 2.4.9-6. See

http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=54868

Now the question is how bad the current Linus/AC kernels are?

Hopefully pretty close since there isn't much NFS related difference between
vanilla and -ac currently. The -ac client has the NFS inode structure in its
own slab being the major change

They are not affected. The RedHat kernel seems to have the (known) bug
in which the grace period isn't reset. My fault for introducing it in
the 2.4.9-ac series...

I haven't gotten round to syncing up the AC kernel to the full reclaim
code that's in Linus' kernel, but Alan has already applied the
following patch (as of 2.4.10-ac12).

Cheers,
Trond
