Scalable Counters
Scalable Statistics Counter
Statistics counters are used in many places in the linux kernel
including storage and network I/O subsystems, scheduler etc.
Since accuracy is not very important, these counters are
non-atomic, but they result in cache line bouncing
among CPUs.
Scalable Statistics Counter
is a feature that provides the support for a low cache-penalty
counter that can be used for statistics gathering.
