Subject: [PATCH 0/6] cputime: Fixes and cleanups on steal time accounting
Date: Thu, 6 Mar 2014 18:56:35 +0100 [thread overview]
Message-ID: <1394128601-26034-1-git-send-email-fweisbec@gmail.com> (raw)
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.
