I have not started looking at 2.6 yet, but somehow I assumed it would
already have the automatic freeze invocation logic in it.

Too bad that it doesn't, but with 2.4 and XFS I initiate the freeze from
user space and don't depend on the patch being installed.  

I assume all of the various filesystems have a way to invoke the freeze
from userspace.  If so, this patch is a nicety, not a neccesity.
