There is no single maintainer of the lockd code. Neil Brown and I tend
to share responsibility for pushing these patches to Linus & Marcelo.

FYI: You will find a number of people who would be interested in
discussing this on the NFS mail list [e-mail]
(although a lot of us are subscribed to linux kernel too). Please just
trot out your patches on either of these lists, and show us what
you've found 8-)
