Hello, Sebastian, Just doing my periodic (but decidedly non-real-time) scan of RCU-related patches in -rt, in this case v5.10.8-rt23: db93e2f1b4b0 ("rcu: Prevent false positive softirq warning on RT") Looks ready for mainline, given CONFIG_PREEMPT_RT. f3541b467fbb ("sched: Do not account rcu_preempt_depth on RT in might_sleep()") If the scheduler maintainers are OK with their part of this patch, looks good to me, given CONFIG_PREEMPT_RT. Feel free to add: Acked-by: Paul E. McKenney <paulmck@xxxxxxxxxxx> d8c5a7d75e08 ("rcutorture: Avoid problematic critical section nesting on RT") This one I need to understand better. I do like the use of local variables to make the "if" conditions less unruly. The rest are in -rcu already: a163ef8687a1 ("rcu: make RCU_BOOST default on RT") Commit 2341bc4a0311 in -rcu. In yesterday's pull request. 5ffd75a96828 ("rcu: Use rcuc threads on PREEMPT_RT as we did") Commit 8b9a0ecc7ef5 in -rcu. In yesterday's pull request. e0b671bca2e7 ("rcu: enable rcu_normal_after_boot by default for RT") Commit 36221e109eb2 in -rcu. In yesterday's pull request. e27ef68731a1 ("rcu: Don't invoke try_invoke_on_locked_down_task() with irqs disabled") This one is in v5.10 mainline. Any reason I shouldn't pull in db93e2f1b4b0 ("rcu: Prevent false positive softirq warning on RT") for v5.13? Thanx, Paul
