Subject: [patch 19/60] kasan: rename print_shadow_for_address to print_memory_metadata
Date: Tue, 22 Dec 2020 12:01:10 -0800 [thread overview]
Message-ID: <20201222200110.QNReXF7AZ%akpm@linux-foundation.org> (raw)
In-Reply-To: <20201222115844.d30aaef7df6f5b120d3e0c3d@linux-foundation.org>
From: Andrey Konovalov <andreyknvl@google.com>
Subject: kasan: rename print_shadow_for_address to print_memory_metadata
This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.
Hardware tag-based KASAN won't be using shadow memory, but will reuse this
function. Rename "shadow" to implementation-neutral "metadata".
No functional changes.
