(The difference > would become apparent with >1 level deep hierarchies.) We are adding two files in this patch series, misc.events and misc.events.local. I think "fail" should go in misc.events.local and its name should be changed to "max". So, both files will have "max" entry but the one in misc.events will refer to the failures in the current cgroup and its children, and the one in misc.events.local will refer to the originating cgroup. > > Regards, > Michal > > [1] https://lore.kernel.org/lkml/20191202191100.GF16681@xxxxxxxxxxxxxxxxxxxxxxxxxxx/ >
