Subject: Re: [RFC PATCH] nfs: Support posix_fadvise(POSIX_FADV_RANDOM) on nfs server.

Hi. Dean.

I have currenlty been having the deep interest about NFS. If I have a
chance to help you for NFSv2, It is a great honor for me.
Acutally I don't know how to contribute something for NFSv2 spec. If
you give me some guide or advice, I will join postively.

Thanks.
