Subject: [PATCH 0/2] Fix nested permission update
Date: Sat, 31 Oct 2020 15:35:00 +0300 [thread overview]
Message-ID: <20201031123502.4558-1-vsementsov@virtuozzo.com> (raw)
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
