Sending in my report now. My issue *maybe* is related to cgroups/docker.
I don't think I saw this issue until I started trying to request
hugepages from a docker container.
But from what I can see, some processes just... do not give up the pages
after they exit. At least not in a way that the kernel can pick up on.
Instead I end up with pages that are not available, I cannot free them,
and I can find no evidence of them in /dev/hugepages, ipcs, or
/proc/*/numa_maps. They are just ghosts!
