I'd expect the subject to be "subprojects: update libvfio-user 
subproject" since that's really what the patch is doing. The 
hw/remote/vfio-user-obj.c update seems to be due to an API change in the 
updated library, so I'd add a sentence mentioning this in the commit 
message.

Otherwise the patch itself seems okay to me, so:

hw/remote is the only consumer of the subproject though...
