Correction:
32% of kernel functions fit into a single cacheline,
55% fit into two cachelines,
70% into three cachelines,
76% into four cachelines
so the tail is longer than my quick read of the graph suggested.
OTOH, probability of use is biased towards smaller functions: we tend
to use smaller, facility functions more frequently.
Thanks,
Ingo
