Subject: [PATCH 5.18 112/181] vmcore: convert copy_oldmem_page() to take an iov_iter
Date: Mon, 27 Jun 2022 13:21:25 +0200 [thread overview]
Message-ID: <20220627111947.945731832@linuxfoundation.org> (raw)
In-Reply-To: <20220627111944.553492442@linuxfoundation.org>
From: Matthew Wilcox (Oracle) <willy@infradead.org>
[ Upstream commit 5d8de293c224896a4da99763fce4f9794308caf4 ]
Patch series "Convert vmcore to use an iov_iter", v5.
For some reason several people have been sending bad patches to fix
compiler warnings in vmcore recently. Here's how it should be done.
Compile-tested only on x86. As noted in the first patch, s390 should take
this conversion a bit further, but I'm not inclined to do that work
myself.
This patch (of 3):
Instead of passing in a 'buf' and 'userbuf' argument, pass in an iov_iter.
s390 needs more work to pass the iov_iter down further, or refactor, but
I'd be more comfortable if someone who can test on s390 did that work.
It's more convenient to convert the whole of read_from_oldmem() to take an
iov_iter at the same time, so rename it to read_from_oldmem_iter() and add
a temporary read_from_oldmem() wrapper that creates an iov_iter.
