Hi, This is an updated version of the inital post after PeterZ made me aware that there are users outside of the module directory. The goal is replace the mix auf rcu_read_lock(), rcu_read_lock_sched() and preempt_disable() with just rcu_read_lock(). I've splitted it into smaller chunks which can be applied/ reviewed independently. I'm just not sure about the cfi patch (28/28) so I added just a comment instead. v1…v2: https://lore.kernel.org/all/20241205215102.hRywUW2A@xxxxxxxxxxxxx/ - Splitted into smaller patches. - Converted all users.
