Subject: [PATCH -tip V2 0/2] kprobes: Fix RCU warning and cleanup

Hi,

Here is a couple of patches which fix suspicious RCU
usage warnings in kprobes.

Anders reported the first warning in kprobe smoke test
with CONFIG_PROVE_RCU_LIST=y. While fixing this issue,
I found similar issues and cleanups in kprobes.

Thank you,

      kprobes: Suppress the suspicious RCU warning on kprobes
      kprobes: Use non RCU traversal APIs on kprobe_tables if possible
