[PATCH v2 03/19] accel/kvm: Convert to ram_block_discard_disable()


From: David Hildenbrand
Subject: [PATCH v2 03/19] accel/kvm: Convert to ram_block_discard_disable()
Date: Wed, 20 May 2020 14:31:36 +0200

Discarding memory does not work as expected. At the time this is called,
we cannot have anyone active that relies on discards to work properly.
