Hi, Here is the version 5 of NOKPORBE_SYMBOL series. This version includes the cleanup patches and features (make blacklist visible, module support) again. And I've added a patch to show all the blacklist functions which includes .entry.text and .kprobes.text(if exist) so that user tools can check the blacklisted functions before setting new probe. This series will fix the kernel crashable "qualitative" bugs of kprobes even with lockdep. But we still have "quantitative" issue which we are discussing on LKML. https://lkml.org/lkml/2013/12/3/788 I'd like to send another series for solving this "quantitative" issue.
