Subject: [PATCH] evm: mark evm_fixmode as __ro_after_init
Date: Thu, 28 Oct 2021 12:26:42 +0100 [thread overview]
Message-ID: <20211028112642.GA1110@raspberrypi> (raw)
From: Austin Kim <austin.kim@lge.com>
The evm_fixmode is only configurable by command-line option and it is never
modified outside initcalls, so declaring it with __ro_after_init is better.
