The PREEMPT_RT patchset does not use do_softirq() function thus trying to filter for do_softirq fails for such kernel:
echo do_softirq ftracetest: 81: echo: echo: I/O error
Choose some other visible function for the test. The function does not have to be actually executed during the test, because it is only testing filter API interface.
This needs -rt patch even on mainline, right?
It is certainly not needed in -stable branches.
I'll drop it, thanks.
