20  * an ioctl file descriptor on an autofs mount that may be covered by
21  * another mount. This situation arises when starting automount(8)
23  * mounts (used for autofs lazy mount/umount of nested mount trees),
181 /* Find the topmost mount satisfying test() */
223  * Open a file descriptor on the autofs mount point corresponding
256 /* Open a file descriptor on an autofs mount point */
296  * Send "ready" status for an existing wait (either a mount or an expire
310  * Send "fail" status for an existing wait (either a mount or an expire
328  * Normally this is set at mount using an option but if we
329  * are reconnecting to a busy mount then we need to use this
330  * to tell the autofs mount about the new kernel pipe fd. In
332  * pipefd we also require that the autofs mount be catatonic.
387  * Make the autofs mount point catatonic, no longer responsive to
388  * mount requests. Also closes the kernel pipe file descriptor.
398 /* Set the autofs mount timeout */
412  * Return the uid and gid of the last request for the mount
414  * When reconstructing an autofs mount tree with active mounts
416  * process uid and gid (or string variations of them) for mount
471 /* Check if autofs mount point is in use */
486  * mount we're looking for a specific mount. In this case
488  * mountpoint or contains a mount, such as a multi-mount
489  * without a root mount. In this case we return 1 if the
490  * path is a mount point and the super magic of the covering
491  * mount if there is one or 0 if it isn't a mountpoint.
494  * lookup the path and check if it is the root of a mount.
496  * mount and if we don't find a match we return fail. If the
497  * located path is the root of a mount we return 1 along with
498  * the super magic of the mount or 0 otherwise.
665 		 * Admin needs to be able to set the mount catatonic in  in _autofs_dev_ioctl()
