From 580a25756a9f639180b29a508f3bdd24c50a936a Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 11 Sep 2023 10:40:15 -0400 Subject: SUNRPC: discard sp_lock sp_lock is now only used to protect sp_all_threads. This isn't needed as sp_all_threads is only manipulated through svc_set_num_threads(), which is already serialized. Read-acccess only requires rcu_read_lock(). So no more locking is needed.
