The kernel will then be placed - on the bad page list and never be reused. - - The offlining is done in kernel specific granuality. - Normally it's the base page size of the kernel, but - this might change. - - The page must be still accessible, not poisoned. The - kernel will never kill anything for this, but rather - fail the offline. Return value is the size of the - number, or a error when the offlining failed.
