Okay, it seems I have to check the Linux Next for the current state of
affairs...

Right. Please double check this still applies after 59458fa4ddb4
("kcsan: Turn report_filterlist_lock into a raw_spinlock") in latest
mainline (or -next). I had to rework that code to make PREEMPT_RT
happy, and at the same time got rid of all this old code. I suppose a
side-effect was switching over to kmalloc_array() and making it look a
bit cleaner as well.

Thanks,
