C++ (Cpp) dec_nrctrs Examples

Example #1

File: virtual.c Project: DanieleDeSensi/mammut

static void vperfctr_free(struct vperfctr *perfctr)
{
	debug_free(perfctr);
	ClearPageReserved(virt_to_page(perfctr));
	free_page((unsigned long)perfctr);
	dec_nrctrs();
}

Example #2

File: virtual.c Project: akennedy-adtran/linux_mmc_2.6.32.9

/* Allocate a `struct vperfctr'. Claim and reserve
   an entire page so that it can be mmap():ed. */

{
	unsigned long page;

	if (inc_nrctrs() != 0)
		return ERR_PTR(-EBUSY);
	page = get_zeroed_page(GFP_KERNEL);
	if (!page) {
		dec_nrctrs();
		return ERR_PTR(-ENOMEM);
	}
	SetPageReserved(virt_to_page((void *)(page)));
	return (struct vperfctr*) page;
}

Example #3
