commit 3c6e5df1f6badec09cdbbff29b16668a92816b68 Author: David Hildenbrand <david@xxxxxxxxxx> AuthorDate: Mon Oct 11 22:10:47 2021 +0200 Commit: Michael Roth <michael.roth@xxxxxxx> CommitDate: Tue Dec 14 08:57:07 2021 -0600 libvhost-user: fix VHOST_USER_REM_MEM_REG skipping mmap_addr We end up not copying the mmap_addr of all existing regions, resulting in a SEGFAULT once we actually try to map/access anything within our memory regions.
