Review request for mesos, Jie Yu and Jan Schlicht.


Added a missing return.

Repository: mesos


In the future, agents will send updates on their total, e.g., when
resource providers are added or removed. As an update to the agent's
total resources currently triggers rescinding of all offered agent
resources, spurious updates can negatively affect in-flight offer

This patch changes the master so that updates introducing no changes
(i.e., the new resources are identical to the old resources) are
dropped and do not trigger rescinding of offers anymore. We also
adjust the handling of oversubscribed agent resources to drop
redundant updates.

Diffs (updated)

  src/master/master.cpp 6d84a26bff970b842b58dfb69dbf232ba5c16a20 




Tested on a number of platforms on internal CI.
