Hi,
The main purpose of this set is to fix a bug on full dynticks configs
where steal time accounting appears to be zero in /proc/stat even
after a few seconds of competing guests running busy loops in a same
host CPU. It's not a regression though as it was there since the
beginning with full dynticks.
So patch [4/6] is the most important. The rest is preparatory work
to fix the bug and various cleanups.
Thanks.
