True.
What about having a single config parameter as a place to put all vhost logs
for all drives for a single instance ? Remove the memfd implementation with all
the memfd shared_memory option ? Replace it with a open+unlink+ftruncate+mmap
approach only.
This way every device would get its own log file and vhost-user backends would
be able to get its file descriptors. (and, of course, allow the security
drivers to do their jobs).
