From 86313c488a6848b7ec2ba04e74f25f79dd32a0b7 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Tue, 17 Jul 2007 18:37:03 -0700 Subject: usermodehelper: Tidy up waiting Rather than using a tri-state integer for the wait flag in call_usermodehelper_exec, define a proper enum, and use that. I've preserved the integer values so that any callers I've missed should still work OK.

This enables the reporting of the Fn key to the input system. As Fn is a dead key for most purposes, it's useful to report it so applications can make use of it. One example is apple_mouse (https://jake.ruivo.org/uinputd/trunk/apple_mouse/) that emulates the second and third keys using a combination of keyboard keys and the mouse button. Other applications may use the KEY_FN as a modifier as well. I've been updating and using this patch for months without problems.
