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? -- Thanks and Regards Srikar -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
