[PATCH 0/2] btrfs-progs: forget removed devices

[Boris Burkov <boris@bur.io>]

To fix bugs in multi-dev filesystems not handling a devt changing under
them when a device gets destroyed and re-created with a different devt,
we need to forget devices as they get removed.

Modify scan -u to take advantage of the kernel taking unvalidated block
dev names and modify udev to invoke this scan -u on device remove.

Boris Burkov (2):
  btrfs-progs: allow btrfs device scan -u on dead dev
  btrfs-progs: add udev rule to forget removed device
