Subject: [PATCH RFC v1 06/26] kasan: compiler.h: rename __no_kasan_or_inline into __no_memory_tool_or_inline
Date: Fri, 18 Oct 2019 11:42:44 +0200 [thread overview]
Message-ID: <20191018094304.37056-7-glider@google.com> (raw)
In-Reply-To: <20191018094304.37056-1-glider@google.com>
As we use it for KMSAN as well now, let's change the name to be more
generic.

Note that __no_kasan_or_inline is currently used only on S390, and KMSAN
patches don't introduce uses of __no_memory_tool_or_inline, so this
patch can be landed later if needed.
