Hi Daisuke, The trace.c extension module is no longer functional as of Linux 4.2 due to a huge rework of the ftrace code which, most notably, changed symbol and structure names from "ftrace..." to "trace...". Can you take a look at addressing those changes, while maintaining backwards compatibility? Thanks, Dave -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
