[PATCH v5 1/2] cpuset: rename cpuset_node_allowed to cpuset_current_node_allowed

[Gregory Price <gourry@gourry.net>]

Rename cpuset_node_allowed to reflect that the function checks the
current task's cpuset.mems.  This allows us to make a new
cpuset_node_allowed function that checks a target cgroup's cpuset.mems.
