[Qemu-devel] [PATCH v4 3/6] vhost: Add temporary memory structure |
Date: |
Wed, 13 Dec 2017 18:08:04 +0000 |
From: "Dr. David Alan Gilbert" <address@hidden>
Add a 2nd 'vhost_memory' structure that will be used to build
the new version as the listener iterates over the address space.
Signed-off-by: Dr. David Alan Gilbert <address@hidden>
