From 9c54b6164eeb292a0eac86c6913bd8daaff35e62 Mon Sep 17 00:00:00 2001 From: Masami Hiramatsu Date: Thu, 17 Apr 2014 17:18:07 +0900 Subject: kprobes, x86: Allow kprobes on text_poke/hw_breakpoint Allow kprobes on text_poke/hw_breakpoint because those are not related to the critical int3-debug recursive path of kprobes at this moment.
