Memory cgroup controller
========================

As of ulatencyd version 0.5.0-3 the memory resource controller mountpoint is not
mounted (and used) by default because the support to the memory cgroup has been
disabled in linux-2.6 since version 2.6.39-2.

To re-enable it the kernel has to be started with the "cgroup_enable=memory"
parameter and the option "memory={"memory"}" (around line 25) in the file
"/etc/ulatencyd/cgroups.conf" has to be decommented. In order to make the change
effective, restart the ulatencyd daemon.

Memory+swap controller
======================

On Debian Linux kernels the CONFIG_CGROUP_MEM_RES_CTLR_SWAP (memsw) option is
disabled. To enable it, the kernel has to be started with the "swapaccount=1"
parameter. ulatencyd will work correctly whether the option is enabled or not.
