Hi Andrew,
If the timeout of an autofs mount is set to zero then umounts
are disabled. This works fine, however the kernel module checks
the expire timeout and goes no further if it is zero. This is
not the right thing to do at shutdown as the module is passed
an option to expire mounts regardless of their timeout setting.
This patch allows autofs to honor the force expire option.
