It's a v2 of the previous set (https://lore.kernel.org/lkml/20210128171222.131380-1-frederic@kernel.org/) minus the patches already applied in rcu/dev. And this is based on latest rcu/dev.
Changelog since v1:
"rcu/nocb: Fix potential missed nocb_timer rearm" * Remove nocb_defer_wakeup reset from do_nocb_deferred_wakeup_common() (paulmck) * Only reset/del if the timer is actually armed * Add secondary potential cause for missed rearm in the changelog
"rcu/nocb: Disable bypass when CPU isn't completely offloaded" * Improve comments on state machine (paulmck) * Add comment (a full quote from Paul) explaining why early flush is enough (paulmck) * Move sanity check to the very end of deoffloading (paulmck) * Clarify some comments about nocb locking on de-offloading (paulmck)
"rcu/nocb: Remove stale comment above rcu_segcblist_offload()" * New patch, reported by (paulmck)
"rcu/nocb: Merge nocb_timer to the rdp leader" * Remove rcu_running_nocb_timer() and its use in rcu_rdp_is_offloaded() debugging since the timer doesn't refer to any rdp offloading anymore. * Only delete nocb_timer when armed, in nocb_gp_wait() * Clarify some comments about nocb locking on de-offloading (paulmck) * Remove stale code "re-enabling" nocb timer on offloading. Not necessary anymore and even buggy.
"timer: Revert "timer: Add timer_curr_running()"" * New patch
