Right.

So the problem is that currently autofs needs to rescan the proc mount
table on every change.   The solution to that is to

 - add a notification mechanism
 - and a way to selectively query mount/superblock information

right?

For the notification we have uevents in sysfs, which also supplies the
changed parameters.  Taking aside namespace issues and addressing
mounts would this work for autofs?

Thanks,
