From ae5b3500856fb9a565470d83033bb91786ec16f1 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Thu, 20 Mar 2025 21:25:01 -0500 Subject: [PATCH] kstrtox: add support for enabled and disabled in kstrtobool() In some places in the kernel there is a design pattern for sysfs attributes to use kstrtobool() in store() and str_enabled_disabled() in show(). This is counterintuitive to interact with because kstrtobool() takes on/off but str_enabled_disabled() shows enabled/disabled. Some of those sysfs uses could switch to str_on_off() but for some attributes enabled/disabled really makes more sense. Add support for kstrtobool() to accept enabled/disabled.
