What does 'none' mean in "mount -t cgroup -o cpuset none /cpuset"

Question

When practising cgroup, we need mount like mount -t cgroup -o cpuset none /cpuset

Would you explain the significance of none here?

Seems it's just a name and I could set it as any string, right?

Is there any file, folder or file contant based on it?

[Here](http://unix.stackexchange.com/questions/136646/what-is-type-none-for-mount-points-and-why-are-mount-points-of-the-same-type-b) it is already answered. — Arnab Nandy, Apr 16 '15 at 12:36

Certain filesystems aren't associated with a physical device (such as a partition or network share, which is what is expected at that point in the mount command) and it is/was customary to use none for these. I've seen a more reasonable approach, using a more descriptive name, eg. cpuset in your case.

Cheers,

Thanks for your answer. So in case I set it as a weird name and is there any thing affected by it? – Qiu Yangfan Apr 16 '15 at 12:45
Anything goes really, but keep in mind that mount/unmount errors use the selected name, so choose sensibly for the sake of your own sanity :-) – Anders R. Bystrup Apr 16 '15 at 12:55
