[PATCH 0/2] Fix nested permission update

[Vladimir Sementsov-Ogievskiy]

Hi! With help of some assertions (patch 2) I've found that
bdrv_drop_intermediate() do nested permission update which in my opinion
may lead to unpredictable behavior.

Vladimir Sementsov-Ogievskiy (2):
  block: make bdrv_drop_intermediate() less wrong
  block: assert that permission commit sets same permissions
