[PATCH 5/7] turbostat: rename num_cores_per_pkg to num_cores_per_node

Show all headers | View raw

turbostat incorrectly assumes that there is one node per package.  As a
result num_cores_per_pkg is not correctly named and is actually
num_cores_per_node.

Rename num_cores_per_pkg to num_cores_per_node.
