Run sudoedit /etc/default/grub in a terminal and edit the GRUB_CMDLINE_LINUX line so it looks like this:

GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1"

Save and exit and then run sudo update-grub and reboot. That should be enough.

I run this command sudoedit/etc/default/grub and edit the grub file by GRUB_CMDLINE_LINUX="cgroup_enable=memory swapaccount=1" after that update-grub and reboot.But now also i got the same warning – user238511 Feb 6 '14 at 14:41

Check your dmesg output, particularly the kernel command line that the arguments were passed to the kernel by grub. I had to edit GRUB_CMDLINE_LINUX_DEFAULT instead. – Tim Potter Jun 18 '14 at 5:32
