Subject: [PATCH -tip 0/5] kprobes: Remove BUG_ON from kprobes
Date: Tue, 21 Aug 2018 18:37:35 +0900	[thread overview]
Message-ID: <153484425558.5385.1484910606397784412.stgit@devbox> (raw)

Hi,

Here are patches to remove BUG_ON from kprobes.

Since BUG_ON() kills the machine, it must not be used
for debugging or assertion. These patches remove
meaningless BUG_ON or replace it with return errors.

Thank you,

      kprobes: Remove meaningless BUG_ON from add_new_kprobe
      kprobes: Remove meaningless BUG_ON from reuse_unused_kprobe
      kprobes: Return error if fail to reuse kprobe instead of BUG_ON
      kprobes: Don't call BUG_ON if there is a kprobe in use on free list
