I never seen this or get a bugreport for SUSE, but IMO this is a kernel bug. 
The kernel should update /proc/mounts before emit the netlink message. How 
long is the delay between the event and change in /proc/mounts?

Btw. We maybe could workaround this with add a short delay befor 
open /proc/mounts (but IMO the kernel need a fix.)
