Hi-

This patch series updates the server-side XDR encoder functions for
NFS versions 2 and 3. The series was available on both test servers
I maintained at last week's virtual bake-a-thon event.

I expect that the only controversial part of the series is the
changes to NFSv3 READDIR and the per-entry encoders. If the reader
has no time for anything else, please have a close look at those.

The series is also available in the for-next topic branch here:
