Status in linux package in Ubuntu:

Status in linux source package in Yakkety:
Fix Released
Bug description:
The perf subsystem provides a rather large attack surface, and system
owners would like a way to disable access to non-root users. This is
already being done in Android and Debian, and I'd like to do the same
on my Ubuntu systems. :)
