Subject: [PATCH 11/18] autofs: Fix Documentation regarding devid on ioctl

From: Tomohiro Kusumi <kusumi.tomohiro@...il.com>

The explanation on how ioctl handles devid seems incorrect.
Userspace who calls this ioctl has no input regarding devid,
and ioctl implementation retrieves devid via superblock.
