From: Konstantin Khorenko <khore...@virtuozzo.com>
This should be a part of commit
127bd48f3385 ("vzstat: Add vzstat module and kstat interfaces")
but depends on task_group::avenrun accounting and thus goes separately.
Signed-off-by: Konstantin Khorenko <khore...@virtuozzo.com>
(cherry-picked from vz8 commit 8325732346ba ("vzstat: Add
kstat_glob.nr_unint_avg real accounting"))
