Miller" <davem@...emloft.net>, Masami Hiramatsu <mhiramat@...nel.org>, linux-kernel@...r.kernel.org Subject: [PATCH -tip 1/5] kprobes: Remove meaningless BUG_ON from disarming process All aggr_probe at this line are already disarmed by disable_kprobe() or checked by kprobe_disarmed(). So this BUG_ON() does meaningless check. Remove it.
