Subject: [PATCH v2] rv/monitors: Move monitor structure in rodata
Date: Tue, 22 Nov 2022 18:36:48 +0100	[thread overview]
Message-ID: <20221122173648.4732-1-acarmina@redhat.com> (raw)
In-Reply-To: <7febf4f5-88d9-7902-e231-af2b6d0d6df0@kernel.org>

It makes sense to move the important monitor structure into rodata to
prevent accidental structure modification.
