It is intended for use when the subsystem wants to return a collection of values that are related in some way, for which a separate control file for each value would make the reporting unwieldy. The advantages of this are: - more standardized output from control files that report similarly-structured data that needs to be parsed programmatically - less boilerplate required in cgroup subsystems - simplifies transition to a future efficient cgroups binary API Signed-off-by: Paul Menage -- -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
