[lxc-devel] [PATCH 22/24] Don't call setup_mount_entries if the list is empty

[Stéphane Graber]

There's no good reason to call setup_mount_entries if we don't have any
lxc.mount.entry. This also avoids an issue on bionic where the tmpfile()
call in setup_mount_entries requires the presence of /tmp which isn't the
case by default.
