Hi!
I would rather see the whitespace cleanup in a separate patch. It's
harder to track what changes were done in a patch if it combines
unrelated changes.
And also this is 1/2, shouldn't there be a second patch that uses this?

OK, I will separate the patch and resend them.

Yes, I should have sent the second patch that uses this, but I faced a problem
below and was still working on it.
I found that setpriority01 with PRIO_USER as root will change system environment,
set the priorities of all specified processes to 19.
Before setpriority(PRIO_USER, root, -20..19):

Well that is kind of expected, since it should operate on all processes
whose user real id matches the who parameter. I guess that the only safe
way how to test this flag is to:
* Pick unused user id and sets it as a real user id
* Start a few processes there
* One of them calls setpriority and checks that all of them got it
