Subject: [patch 08/29] lockup_detector: Mark hardlockup_detector_disable() __init
Date: Thu, 31 Aug 2017 09:16:06 +0200 [thread overview]
Message-ID: <20170831073053.601705530@linutronix.de> (raw)
In-Reply-To: 20170831071558.995235362@linutronix.de
[-- Attachment #1: lockup_detector--Mark-hardlockup_detector_disable---__init.patch --]
[-- Type: text/plain, Size: 608 bytes --]
The function is only used by the KVM init code. Mark it __init to prevent
creative abuse.
