Hi again,
Last time i forgot to CC the list...just to follow up on the previous
email.
I've created a diff with XFS (cvs version) and preempt against
2.4.21-pre2 which boots and seems to work ok (have run it for ~2 days).
The diff+details are on http://www.blazebox.homeip.net:81/~paul/linux .
Regards,
Paul B.
P.S. Happy New Year to all on the list!
