config DEBUG_PAGEALLOC bool "Debug page memory allocations" depends on DEBUG_KERNEL && ARCH_SUPPORTS_DEBUG_PAGEALLOC depends on !HIBERNATION || !PPC && !SPARC depends on !KMEMCHECK ---help--- Unmap pages from the kernel linear mapping after free_pages(). This results in a large slowdown, but helps to find certain types of memory corruption. config WANT_PAGE_DEBUG_FLAGS bool config PAGE_POISONING bool "Debug page memory allocations" depends on DEBUG_KERNEL && !ARCH_SUPPORTS_DEBUG_PAGEALLOC depends on !HIBERNATION select DEBUG_PAGEALLOC select WANT_PAGE_DEBUG_FLAGS ---help--- Fill the pages with poison patterns after free_pages() and verify the patterns before alloc_pages(). This results in a large slowdown, but helps to find certain types of memory corruption. This option cannot be enabled in combination with hibernation as that would result in incorrect warnings of memory corruption after a resume because free pages are not saved to the suspend image.
