LinuxCon + ContainerCon North America 2016

The kernel team at Facebook works on both features and fixes for the
upstream Linux community, as well as pulling in patches to apply to the
kernels run in the Facebook production fleet. This is done in order to
support new and upcoming hardware variations, as well as fix standing
issues in the environment and improve performance. We aim to roll out a
new kernel to a large portion of the fleet, as often as possible.

In this talk, we will explore how the kernel PE team has worked to
automate the build and install process, rolling a canary of the newly
built kernels every day and gathering thousands of tests to validate
each kernel before we push out to other tiers to upgrade.
We run a series of integration tests across multiple hardware types and
generations, do performance and correctness tests on the newly built
kernels, and release the kernel through multiple canaries
