Subject: [PATCH v6 0/3] convert write_threads, write_version and write_ports to netlink commands

From: Lorenzo Bianconi <[email-masked]>
Date: Sat, 20 Jan 2024 18:33:29 +0100

Introduce write_threads, write_version and write_ports netlink
commands similar to the ones available through the procfs.

Changes since v5:
- for write_ports and write_version commands, userspace is expected to provide
  a NFS listeners/supported versions list it want to enable (all the other
  ports/versions will be disabled).
- fix comments
- rebase on top of nfsd-next
Changes since v4:
- rebase on top of nfsd-next tree
Changes since v3:
- drop write_maxconn and write_maxblksize for the moment
- add write_version and write_ports commands
Changes since v2:
- use u32 to store nthreads in nfsd_nl_threads_set_doit
- rename server-attr in control-plane in nfsd.yaml specs
Changes since v1:
- remove write_v4_end_grace command
- add write_maxblksize and write_maxconn netlink commands

This patch can be tested with user-space tool reported below:
