Benjamin Mahler updated MESOS-8075:
-----------------------------------
Description:
We want to add a new {{ReadWriteLock}} similar to {{Mutex}}, which can provide
better concurrecy protection for mutual exclusive actions, but allow high
concurrency for actions which can be performed at the same time.
One use case is image garbage collection: the new API
{{provisioner::pruneImages}} needs to be mutually exclusive from
{{provisioner::provision}}, but multiple {{{provisioner::provision}} can
concurrently run safely.
