CGroup API files: update cpusets to use cgroup structured file API

Browse source

Many of the cpusets control files are simple integer values, which don't
require the overhead of memory allocations for reads and writes.

Move the handlers for these control files into cpuset_read_u64() and
cpuset_write_u64().
