The poll-ability of /proc/self/mountinfo is a feature that has been
added specifically for that one file. Only very few other files in /proc
can do this (only swaps and the host/domainname files afaik). If you
want this for for other files in /proc you'd first have to patch the
kernel.

That said, file locking on Linux/Unix is unusably broken anyway, why
would you want to monitor that?
