[PATCH v2 0/5] nfsd/sunrpc: allow starting/stopping pooled NFS server via netlink

From: Jeff Layton
Date: Thu Jun 13 2024 - 08:19:22 EST


This is a resend of the patchset I sent a little over a week ago, with
a couple of new patches that allow setting the pool-mode via netlink.

This patchset first attempts to detangle the pooled/non-pooled service
handling in the sunrpc layer, unifies the codepaths that start the
pooled vs. non-pooled nfsd, and then wires up the new netlink threads
interface to allow you to start a pooled server by specifying an
array of thread counts.
