Ah! You're right, that's the reason! When the kernel is locked down ftrace is explicitly disabled. To confirm that, you should have 0 in /proc/sys/kernel/ftrace_enabled. Can you try to set it back to 1 and see if kprobe-perf works after that? Otherwise I'll figure out an alternative way to trace d

OK, so we know that it's not related to the memory cgroup subsystem. Another reason of such unexpected swapping activity could be due to memory compaction code that is triggering some direct memory reclaim and forcing to swap out pages. What do you have in /proc/sys/vm/swappiness? Could you try t
