Josh, thanks for testing. For kprobe fault handler testing you can run the
below script. Basically this tries to access userspace
address from kprobe prehandler.
-----------------------------
probe syscall.*, syscall.*.return {
if (pid() == target()) {
if (returnp)
printf("%d\n", returnval())
else
printf("%s (%s) = ", name, argstr)
}
}
