Hi,
When I run ./testsuite/buildok/six.stp by "stap -gv" command, it
crashed, the script is like this
probe kernel.inline("context_switch") {
log ("found an inline function")
}
Does there exist some critical code area in kernel code where probe
point can not be put? And such as context_switch, it can not be probed
by trap method of kprobe.
Regards
Bibo,mao
