Re: [Crash-utility] trace.c extension module needs to be updated

It uses this construct in the relevant locations to pick the correct version: MAX(MEMBER_OFFSET("ftrace_event_call", ...), MEMBER_OFFSET("trace_event_call", ...)) Note that I also added a gdb_set_crash_scope() call to init_offsets() because there are multiple, different, "struct ring_buffer" declarations in the kernel, and for whatever reason, crash was initially picking up the wrong one from "kernel/events/internal.h". Can you verify that this patch is sufficient and test its functionality? Or if you prefer, can you come up with your own solution?
