21  * an ioctl file descriptor on an autofs mount that may be covered by
22  * another mount. This situation arises when starting automount(8)
24  * mounts (used for autofs lazy mount/umount of nested mount trees),
187 /* Find the topmost mount satisfying test() */
229  * Open a file descriptor on the autofs mount point corresponding
262 /* Open a file descriptor on an autofs mount point */
302  * Send "ready" status for an existing wait (either a mount or an expire
316  * Send "fail" status for an existing wait (either a mount or an expire
334  * Normally this is set at mount using an option but if we
335  * are reconnecting to a busy mount then we need to use this
336  * to tell the autofs mount about the new kernel pipe fd. In
338  * pipefd we also require that the autofs mount be catatonic.
393  * Make the autofs mount point catatonic, no longer responsive to
394  * mount requests. Also closes the kernel pipe file descriptor.
405  * Set the autofs mount expire timeout.
409  * mounts because there's a distinct mount corresponding to each of
416  * setting the per-dentry expire timeout the mount point name is passed
420  * Setting the autofs mount expire timeout sets the timeout in the super
425  * set which disables expiration for the mount point, lastly the flag
