Rao" <naveen.n.rao@...ux.vnet.ibm.com>, Anil S Keshavamurthy <anil.s.keshavamurthy@...el.com>, "David S . Miller" <davem@...emloft.net>, Masami Hiramatsu <mhiramat@...nel.org>, linux-kernel@...r.kernel.org Subject: [PATCH -tip 2/5] kprobes: Remove meaningless BUG_ON from add_new_kprobe Before calling add_new_kprobe(), aggr_probe's GONE flag and kprobe GONE flag are cleared. We don't need to worry about that flag at this point.
