Subject: [PATCH 05/12] module: move check_modinfo() early to early_mod_check()
Date: Sun, 19 Mar 2023 14:27:39 -0700 [thread overview]
Message-ID: <20230319212746.1783033-6-mcgrof@kernel.org> (raw)
In-Reply-To: <20230319212746.1783033-1-mcgrof@kernel.org>
This moves check_modinfo() to early_mod_check(). This
doesn't make any functional changes either, as check_modinfo()
was the first call on layout_and_allocate(), so we're just
moving it back one routine and at the end.
This let's us keep separate the checkers from the allocator.
