From 80744cc92207baa913ac9575374738b6298032eb Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Tue, 4 Mar 2014 07:57:43 -0300 Subject: UBI: block: Use ENOSYS as return value when CONFIG_UBIBLOCK=n In order to have a way of distinguishing an invalid ioctl from a not supported (but otherwise valid) ioctl, this commit changes the return value of the ioctl stubs from ENOTTY to ENOSYS. This will be useful to report more accurate error messages from userspace tools.
