- * Large rounds allocation sizes up to MAX(vm_kernel_page_size, page_size).
- * This provides better death row caching performance when vm_kernel_page_size > page_size.
- * The kernel allocates pages of vm_kernel_page_size to back our allocations,
- * so there is no additional physical page cost to doing this.
- * Guard pages are the same size to ensure the full vm allocation size is a multiple of MAX(vm_kernel_page_size, page_size).
