Do you mean a hardcoded value of some number of micros, or literally
sched_min_granularity / 8? I don't think the latter is necessary, and
indeed can lead to weirdness if min_gran is too small or too large. I
don't think the concept of what a short duration task is should
expand/contract with min_gran.

Best,
