[Linux] psutil module regression bug in psutil.cpu_count(logical=False)

[ewilts]

Platform

• { RHEL7.6}
• { psutil version: python3 -c "import psutil; print(psutil.version)" } 5.7.2
• { python version } 3.6.5

psutil.cpu_count(logical=False)
returns in incorrect number of physical cores.

(RHEL7) [11:44 ed.wilts@csi196 sarc] > python3
Python 3.6.5 (default, Sep 16 2019, 14:55:33)
[GCC 8.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

import psutil
physical = psutil.cpu_count(logical=False)
physical
15

Compare with phython2 and psutil 5.0.1 on this same system:
[11:46 ed.wilts@csi196 ~] > python2 -c "import psutil; print(psutil.version)"
5.0.1
