Bug description
I have a script. The script was able to work before, but it cannot work now. This is the output of the script.

$ python disk.py 
Traceback (most recent call last):
  File "disk.py", line 19, in <module>
    print(next(start(3)))
  File "disk.py", line 7, in start
    data = psutil.disk_io_counters(perdisk=False)
  File "/usr/lib/python3.8/site-packages/psutil/__init__.py", line 2168, in disk_io_counters
    rawdict = _psplatform.disk_io_counters(**kwargs)
  File "/usr/lib/python3.8/site-packages/psutil/_pslinux.py", line 1125, in disk_io_counters
    for entry in gen:
  File "/usr/lib/python3.8/site-packages/psutil/_pslinux.py", line 1098, in read_procfs
    raise ValueError("not sure how to interpret line %r" % line)
ValueError: not sure how to interpret line '   8       0 sda 23531 18723 1862205 9367 10550 14296 455716 11521 0 17907 8067 0 0 0 0 1251 3221\n'

Downstream issue.

Test results
{ output of python -c psutil.tests (failures only, not full result) } Sorry, Cloning psutil repo takes too much time for the network here. Please let me know if you really need the test results.

I just released a new version which fixes this issue.
