Given that Patrick seems > to be okay with the 'default' now, does this look good to you too? There's only two files with "sched_rt" and they are tightly coupled (they define how much an RT task may use the CPU). My question is, is this "sched_rt_default_util_clamp_min" related in any way to those other two files that start with "sched_rt", or is it more related to the files that start with "sched_util_clamp"? If the latter, then I would suggest using "sched_util_clamp_min_rt_default", as it looks to be more related to the "sched_util_clamp_min" than to anything else. -- Steve
