[PATCH 2/3] autofs - make disc device user accessible

[Ian Kent]

The autofs miscellanous device ioctls that shouldn't require
CAP_SYS_ADMIN need to be accessible to user space applications in
order to be able to get information about autofs mounts.

The module checks capabilities so the miscelaneous device should
be fine with broad permissions.
