Another case
perf probe do_fork clone_flags now looks for variable clone_flags in
kernel function do_fork.
But if we allow to trace perf probe zsh zfree; then
'perf probe do_fork clone_flags' should it check for do_fork executable
or not? If it does check and finds one, and searches for clone_flags
function and doesnt find, then should it continue with searching the
kernel?
