Subject: [PATCH v2 0/9] A few more cpuidle vs rcu fixes
Date: Thu, 26 Jan 2023 16:08:29 +0100 [thread overview]
Message-ID: <20230126150829.087606759@infradead.org> (raw)
0-day robot reported graph-tracing made the cpuidle-vs-rcu rework go splat.
These patches appear to cure this, the ftrace selftest now runs to completion
without spamming scary messages to dmesg.
Since v1:
- fixed recursive RCU splats
- fixed psci thingies for arm (null)
- improved the tracing WARN (rostedt)
- fixed TRACE_PREEMPT_TOGGLE (null)
