Subject: [PATCH] kstrtox: Add support for enabled and disabled in kstrtobool()
Date: Thu, 20 Mar 2025 21:25:01 -0500 [thread overview]
Message-ID: <20250321022538.1532445-1-superm1@kernel.org> (raw)
From: Mario Limonciello <mario.limonciello@amd.com>
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.
