Hi Petr,

Sorry for picking up this old thread, but I noticed your attached
ftrace test script and would like to ask for your permission to
include it in

        https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git

which is GPLv2. If you kindly agree, I'll run it actively for testing
the upstream linux kernels.

Thanks,
Fengguang
