Review request for mesos, Andrei Sekretenko and Benjamin Mahler.


Added benchmark result in the description.

Repository: mesos

Description (updated)

A framework is tracked under the role if the framework:
(1) is subscribed to the role;
(2) has resources allocated under the role.

(2) could be true without (1). This is because we allow
frameworks to update their roles without revoking their
allocated or offered resources.

This patch recognizes this fact and encapsulates the related
checks in the helper.

Benchmark result: no major performance impact.
