Hi, v2 of a proposed RCU change to make rcu_normal_after_boot feature usable on PREEMPT_RT as well, as it turns out it's useful on RT as well on NO_HZ_FULL configurations. v2 gained an additional patch to revise rcu update module parameters permissions (as suggested during v1 review [1]). Changes wrt v1: - Restrict the option to !PREEMPT_RT || NO_HZ_FULL (Paul, Sebastian) - Change module params permissions (Paul) (02/02) Thanks, Juri v1 - https://lore.kernel.org/lkml/20210805080123.16320-1-juri.lelli@xxxxxxxxxx/ Juri Lelli (2): rcu: Make rcu_normal_after_boot writable again rcu: Make rcu update module parameters world-readable kernel/rcu/tree_exp.h | 1 - kernel/rcu/update.c | 8 ++++---- 2 files changed, 4 insertions(+), 5 deletions(-) -- 2.31.1
