Message-ID: <cb8a682e4bba4dbddd2bd8aca7f8c02fea89639b.1601565471.git.gustavoars@kernel.org> Date: Thu, 1 Oct 2020 10:26:34 -0500 From: "Gustavo A. R. Silva" <gustavoars@...nel.org> To: linux-kernel@...r.kernel.org Cc: linux-hardening@...r.kernel.org, Andrew Morton <akpm@...ux-foundation.org>, "Gustavo A. R. Silva" <gustavoars@...nel.org> Subject: [PATCH 3/3][next] lib/stackdepot.c: Use array_size() helper in jhash2() Use array_size() helper instead of the open-coded version in jhash2(). These sorts of multiplication factors need to be wrapped in array_size(). Also, use the preferred form for passing the size of an object type. Signed-off-by: Gustavo A. R.
