- * Using a dynamic percpu 'int' variable has a cost :
- * 1) Extra dereference
- * Current per_cpu_ptr() implementation uses an array per 'percpu variable'.
- * 2) memory cost of NR_CPUS*(32+sizeof(void *)) instead of num_possible_cpus()*4
- *
- * This pcounter implementation is an abstraction to be able to use
- * either a static or a dynamic per cpu variable.
- * One dynamic per cpu variable gets a fast & cheap implementation, we can
- * change pcounter implementation too.
