Hi,
No code change in this v2, only changelogs:
* Add tags from Valentin and Sebastian
* Remove last reference to SEGCBLIST_SOFTIRQ_ONLY (thanks Valentin)
* Rewrite changelog for "rcu/nocb: Check a stable offloaded state to manipulate qlen_last_fqs_check"
after off-list debates with Paul.
* Remove the scenario with softirq interrupting rcuc on
"rcu/nocb: Limit number of softirq callbacks only on softirq" as it's
probably not possible (thanks Valentin).
* Remove the scenario with task spent scheduling out accounted on tlimit
as it's not possible (thanks Valentin)
(see "rcu: Apply callbacks processing time limit only on softirq")
* Fixed changelog of
"rcu/nocb: Don't invoke local rcu core on callback overload from nocb kthread"
(thanks Sebastian).
