NeilBrown 9fa4eb8e49 autofs: sanity check status reported with AUTOFS_DEV_IOCTL_FAIL ... If a positive status is passed with the AUTOFS_DEV_IOCTL_FAIL ioctl, autofs4_d_automount() will return ERR_PTR(status) with that status to follow_automount(), which will then dereference an invalid pointer. So treat a positive status the same as zero, and map to ENOENT. See comment in systemd src/core/automount.c::automount_send_ready().
