Nor would I advocate doing so. I added two 'constants' I wanted to be able to test them so I updated Robert's patch... Two questions for you.
1. Do you have any comments/suggestsion on the ptg_B0 patch?
2. I have been playing with using user and thread penalties together. - they often interact badly. Using just one works very well. This can be fixed - but gets messy. Alternately, I am thinking about implementing per user policies. ie.
a. govern thread groups b. govern all threads, ignoring groups, for a user c. govern processes for a user
This can be done cleanly. Would something along the lines of sys_nice be the way to implement the kernel side of the user interface to this?
