Care to describe what you are doing/planning, is this the knfsd work in
progress?

Alexei has been volunteered by me to work on read_inode on the assumption that
read_inode cleanup is taking too long, perhaps it is moving along more than I
had feared? Poor knfsd interaction is really the last barrier to widespread
deployment of reiserfs in large sites for NFS fileserver usage, so I am sure you
can understand the importance it has to us.
