-    # Prepare cpusets that are pre-defined by Android. Inside Microdroid, these however don't mean
-    # much because the mapping from vCPUs to physical CPUs are quite flexible; a VM can be started
-    # with any number of vCPUs and we in general can't be sure that vCPU N is a big core or a little
-    # core. These nodes are provided just to satisfy the code which puts a PID to a specific cpuset.
