Subject: [PATCH v3 6/6] pstore/ram: Adjust module param permissions to reflect reality
Date: Wed,  6 May 2020 14:15:23 -0700	[thread overview]
Message-ID: <20200506211523.15077-7-keescook@chromium.org> (raw)
In-Reply-To: <20200506211523.15077-1-keescook@chromium.org>

A couple module parameters had 0600 permissions, but changing them would
have no impact on ramoops, so switch these to 0400 to reflect reality.
