Subject: [PATCH 10/11] rcu/nocb: Remove SEGCBLIST_KTHREAD_CB
Date: Thu, 30 May 2024 15:45:51 +0200

This state excerpt from the (de-)offloading state machine was used to
implement an ad-hoc kthread parking of rcuo kthreads. This code has
been removed and therefore the related state can be erased as well.
