Subject: [patch 0/2] vmstat: Speedup and Cleanup
Date: Mon, 22 Feb 2016 12:10:40 -0600 [thread overview]
Message-ID: <20160222181040.553533936@linux.com> (raw)
I have not been too satisfied with the recent code changes and in
particular not fond of the races and the performance regressions
I have seen. So this is an attempt to address those by making some
small code changes and by removing the cpu_stat_off cpumask which
was the reason for the races.
