Public bug reported:

Glancing at dmesg, i'm testing that boot parameter, but got surprised
about the result:

[    0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.11.0-11-generic root=UUID=9e61e83e-bca9-43cf-aa90-5a68892213fa ro crashkernel=384M-2G:64M,2G-:128M cgroup_disable=memory
[    0.000000] Disabling memory control group subsystem

so it seems working; but later i'm seeing:

[    0.008534] Initializing cgroup subsys memory
[    0.008590] Initializing cgroup subsys devices
[    0.008636] Initializing cgroup subsys freezer
[    0.008682] Initializing cgroup subsys blkio
[    0.008728] Initializing cgroup subsys perf_event
[    0.008776] Initializing cgroup subsys hugetlb

thats making me confused; i was beleiving that all these processes been
replaced by zram process inside the recent kernels. Am i wrong ?
