Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      .@paulmckrcu Would it be possible to do "norcu" as "synchronize on every return to userspace and every cpu_idle entry"?

      If you don't mind long loops in the kernel stalling RCU and OOMing your system, yes... But what are you trying to achieve?

      Unpredictable and possibly unbounded memory usage and performance characteristics and seemingly impossible-to-verify logic.

      Or rather, trying to avoid those things. So frustrating debugging this stuff when simple rwlocks & no alloc would've sufficed.

      What I'm trying to say is it'd be nice to have an option that doesn't depend on the scheduler to collect, does it sync. instead.

      : But the real problem was not the scheduler, but rather timers, correct? Or am I behind the times in your troubleshooting?

      I don't know, This thread is inspired by but in some sense orthogonal to current stall problem.

      When you get the timers fixed, let's look again.

      Well, when I get whatever the regression is fixed. Not sure if it's timer, scheduler, rcu, or elsewhere just affecting them.
