Yyou might avoid the loop kmalloc does to hunt
for  the right size..

void * kmalloc (size_t size, int flags)
{
        cache_sizes_t *csizep = cache_sizes;

        for (; csizep->cs_size; csizep++) {
                if (size > csizep->cs_size)
                        continue;
                return __kmem_cache_alloc(flags & GFP_DMA ?
                         csizep->cs_dmacachep : csizep->cs_cachep, flags);
        }
        return NULL;
}


thanks,
