[LIB] pcounter : unline too big functions
Before pushing pcounter to Linus tree, I would like to make some adjustments.
Goal is to reduce kernel text size, by unlining too big functions.
When a pcounter is bound to a statically defined per_cpu variable,
we define two small helpers functions. (No more folding function
using the fat for_each_possible_cpu(cpu) ... )
static DEFINE_PER_CPU(int, NAME##_pcounter_values);
static void NAME##_pcounter_add(struct pcounter *self, int val)
{
__get_cpu_var(NAME##_pcounter_values) += val;
}
static int NAME##_pcounter_getval(const struct pcounter *self, int cpu)
{
return per_cpu(NAME##_pcounter_values, cpu);
}
Fast path is therefore unchanged, while folding/alloc/free is now unlined.
This saves 228 bytes on i386
