Nice! Now the only thing missing is gettind kdb in mainline and a trace
reader in kdb ;-)
Any idea how easy it is to reuse the crash/gdb code for looking at crash
dumps through kgdb?
Btw, the Cc list here seems to be a very strong indicator that we
should have a linux-trace at vger list, I already noticed this for tons
of other tracing patches.
