Hi Thomas,
We noticed ltp/syscalls test regression on
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched/idle
commit: c365c292d05908c6ea6f32708f331e21033fe71d ("sched: Consider pi boosting in setscheduler()")
Thanks,
Fengguang

Both patches can fix the LTP regression.
We applied each of Juri's and Kirill's patches on top of Thomas' commit,
and here are the comparisons:
