I've been using the patch which I submitted for 3 months
now on both 2.1.7.1 and 2.2.1 machines with no problems
that seem to be related to it. I checked the current
source today, and it looks like the problem has not
been fixed by the lite2 merge or any of the work that
has gone on.
I guess anyone that knows the vfs stuff well should be
able to review the patch quite quickly.
David.
