v2: - Just extend the shrink sysfs file to shrink all memcg caches without adding new semantics. - Add a patch to report the time of the shrink operation. This patchset enables the slab/shrink sysfs file to shrink all the memcg caches that are associated with the given root cache. The time of the shrink operation can now be read from the shrink file.
