We use tracing subsystem very well when kernel is alive.
But we also want to get help from tracing when kernel is core-dump.
This patch is for this purpose. It makes tracing can act as a
flight recorder, we can find what have happen from the events.
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@vger list, I already noticed this for tons
of other tracing patches.
