Subject: [patch 01/12] x86/entry: Fix instrumentation annotation
Date: Thu, 04 Feb 2021 21:49:04 +0100 [thread overview]
Message-ID: <20210204211154.091926005@linutronix.de> (raw)
In-Reply-To: 20210204204903.350275743@linutronix.de
Embracing a callout into instrumentation_begin() / instrumentation_begin()
does not really make sense. Make the latter instrumentation_end().
