[PATCH 0/3] nfsd/sunrpc: allow starting/stopping pooled NFS server via netlink

From: Jeff Layton
Date: Tue Jun 04 2024 - 17:08:24 EST


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.

FWIW, eventually I'd like to wire up the pool_mode setting to netlink as
well. I took a stab at adding a pool_mode parameter to the set_threads
interface, but I think that's the wrong approach. By the time we call
set_threads, we've usually already allocated the serv. I think pool_mode
setting has to be done with new netlink call. I'll probably tackle that
in a later patchset.
