Subject: [RFC PATCH v2 0/3] perf/tracefs: Container-aware tracing support

This RFC patch set supports filtering container specific events
when perf tool is executed inside a container. The patches apply
cleanly on v4.7.0-rc7

Changes from v1:
1/3. Revived earlier approach[1] with cgroup namespace instead
     of pid namespace
2/3. New patch that adds instance support for uprobe events in
     tracefs filesystem
3/3. New patch that adds "newinstance" mount option for tracefs
     filesystem
