Linus Torvalds ccfff0a2bd virtio-mem: support VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE ... Support the VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE feature in virtio-mem, now that "accidential" access to logically unplugged memory inside added Linux memory blocks is no longer possible, because we: 1. Removed /dev/kmem in commit bbcd53c960 ("drivers/char: remove /dev/kmem for good") 2. Disallowed access to virtio-mem device memory via /dev/mem in commit 2128f4e21a ("virtio-mem: disallow mapping virtio-mem memory via /dev/mem") 3. Sanitized access to virtio-mem device memory via /proc/kcore in commit 0daa322b8f ("fs/proc/kcore: don't read offline sections, logically offline pages and hwpoisoned pages") 4. Sanitized access to virtio-mem device memory via /proc/vmcore in commit ce2814622e ("virtio-mem: kdump mode to sanitize /proc/vmcore access") The new VIRTIO_MEM_F_UNPLUGGED_INACCESSIBLE feature that will be required by some hypervisors implementing virtio-mem in the near future, so let's support it now that we safely can.
