(Updated June 29, 2016, 12:25 a.m.) Review request for mesos and Benjamin Mahler. Changes ------- Rebased Bugs: MESOS-5562 https://issues.apache.org/jira/browse/MESOS-5562 Repository: mesos Description (updated) ------- Previously, the `NvidiaGpuAllocator` component was created directly inside the `NvidiaGpuIsolatorProcess` even though it was designed to be used by multiple containerizers at the same time. To allow for simultaneous access, we created a new `NvidiaComponents` class to hold an `NvidiaGpuAllocator` instance and pass it to each containerizer as it is created. This component can easily be extended to include more cross-containerizer components later on. We create the `NvidiaComponents` instance inside `Containerizer::create()` and pass it to both the docker containerizer and the mesos containerizer when they are created. The docker containerizer currently doesn't do anything with this information, but its interface has been updated to accomodate it. The mesos containerizer has been updated to pass this all the way down to the `NvidiaGpuIsolatorProcess` and exploit it.
