Another weird bug appeared concerning qemu namespaces. Basically the problem is as follows: 1) Issue an API that causes libvirt to create a node in domain's namespace, say /dev/nvme0n1 with 8:0 as major:minor (the API can be attach-disk for instance). Or simply create the node from a console by hand. 2) Detach the disk from qemu. 3) Do something that makes /dev/nvme0n1 change it's minor number. 4) Try to attach the disk again. The problem is, in a few cases - like disk-detach - we don't remove the corresponding /dev node from the mount namespace (because it may be used by some other disk's backing chain). But this creates a problem, because if the node changes its MAJ:MIN numbers we don't propagate the change into the domain's namespace. We do plain mknod() and ignore EEXIST which obviously is not enough because it doesn't guarantee that the node has updated MAJ:MIN pair.
