H A D | rcu_segcblist.h | diff d97b0781 Fri Nov 13 05:13:19 MST 2020 Frederic Weisbecker <frederic@kernel.org> rcu/nocb: De-offloading CB kthread To de-offload callback processing back onto a CPU, it is necessary to clear SEGCBLIST_OFFLOAD and notify the nocb CB kthread, which will then clear its own bit flag and go to sleep to stop handling callbacks. This commit makes that change. It will also be necessary to notify the nocb GP kthread in this same way, which is the subject of a follow-on commit.
