Hi All,
Here's a buch of patches that slightly improve the ondemand/conservative code on top of the current linux-next branch of my tree (linux-pm.git).
They don't change the way things work fundamentally, but some minor differences may be noticeable.
[1/9] Do not do atomic_inc() in gov_cancel_work() as there's no reason to do it (new version).
[2/9] Avoid atomic ops in scheduler paths if not absolutely necessary (new version).
[3/9] Fix computation of the contribution from nice in dbs_check_cpu().
[4/9] Clean up load-related computations in the common governor code.
[5/9] Get rid of the ->gov_check_cpu callback.
[6/9] Make store_sampling_rate() reset the sample delay to 0 (instead of setting it to the new sampling rate) to avoid weird interactions with the ondemand governor.
[7/9] Move rate_mult to struct policy_dbs_info.
[8/9] Simplify conditionals in od_dbs_timer().
[9/9] Use microseconds in computations related to sample delay.
The series have been (lightly) tested on Toshiba Portege R500.
Thanks, Rafael
