No. you don't need why userland folks want namespaces. Even though you don't
need namespaces. It doesn't good reason to refuse another use case.
This is tangent to the discussion, we need to revisit why an application
other than a daemon managing a set of memcgs would ever need to know the
information in /proc/meminfo. No use-case was ever presented in the
changelog and its not clear how this is at all relevant. So before
changing the kernel, please describe how this actually matters in a real-
world scenario.
Huh? Don't you know a meanings of a namespace ISOLATION? isolation mean,
isolated container shouldn't be able to access global information. If you
want to lean container/namespace concept, tasting openvz or solaris container
is a good start.
But anyway, I dislike current implementaion. So, I NAK this patch too.
