And even filter the stack trace on specific fields of the event. # cd /sys/kernel/debug/tracing # echo "stacktrace if common_pid == $$ && reason == 3" \ > events/tlb/tlb_flush/trigger # cat trace bash-1103 [003] ...1 1290.100133: tlb_flush: pages:-1 reason:local mm shootdown (3) bash-1103 [003] ...2 1290.100140: <stack trace> => copy_process.part.39 => _do_fork => SyS_clone => do_syscall_64 => return_from_SYSCALL_64 -- Steve -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
