Re: [PATCH 2/2] cgroup: add xattr support

Hello, Lennart, Li.

Two things.

* Probably I'm missing something but isn't the systemd cgroup
hierarchy already managed by systemd? If so, I don't see how
managing tmpfs on the side would noticeably make things more
fragile. It would take a bit more care after, for example, restart
but it shouldn't be too complex, no?

* FS attributes already being used for userland information seems like
a good argument, but we shouldn't add separate specialized xattr
implementation to different pseudo filesystems. For it to be
acceptable, it should be a libfs thing easily applicable to any
pseudo FS and definitely shouldn't be using kmem for storage.

Thanks.
