disk_io_counters() fails on Linux kernel 4.19

When running on 4.19.0-1.el7.elrepo.x86_6, calling disk_io_counters() raises ValueError:

temporary fix for python 2.7:

sed -i  's#flen == 14:#flen == 14 or flen == 18:#g'  /usr/local/lib/python2.7/dist-packages/psutil/_pslinux.py

@giampaolo yes, latest git version works. Do you have any plans on releasing a new version to PyPI?
