If using suspend-blockers,
Please explain to me how:
- I will avoid the cpu going into some idle state for which the wakeup latency is larger than my RT app fancies?
- to avoid some tasks from being serviced by the filesystems whilst others are? (ionice on steroids).
- does my sporadic task (with strict bandwidth budget) not suffer bandwidth inversion?
suspend blockers do a bit of each of that, but none of it in a usable fashion.
