Subject: [PATCH mm v10 07/42] kasan: only build init.c for software modes
Date: Fri, 13 Nov 2020 23:15:35 +0100 [thread overview]
Message-ID: <a1864343953031cddc2cca424d9b7f50ddf971d4.1605305705.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1605305705.git.andreyknvl@google.com>
This is a preparatory commit for the upcoming addition of a new hardware
tag-based (MTE-based) KASAN mode.
The new mode won't be using shadow memory, so only build init.c that
contains shadow initialization code for software modes.
No functional changes for software modes.
