Subject: Re: OFD ("file private") locks and NFS

Hi Jeff,

Something which came up on the last Ganesha conn call is that we have
a pretty strong need for some ability to wait on a set of locks, and perhaps
receive events.  Frank Filz believed that you had made a proposal which
would cover this.  Can you elaborate on that?

Thanks,

Matt
