[PATCH nfs-utils v2 00/16] exportfs/exportd/mountd: allow them to use netlink for up/downcalls

[Jeff Layton <jlayton@kernel.org>]

Minor revision to rebase onto recent upstream changes. Original cover
letter follows:

This adds support for the new netlink-based upcalls and downcalls in
mountd, exportd and exportfs. With this, mountd is no longer reliant on
/proc for sunrpc cache upcalls.

There are also a few bugfixes and cleanups for existing code and
documentation too.
