Subject: [PATCH v3 mm 11/13] kasan: inline HW_TAGS helper functions
Date: Fri, 5 Feb 2021 18:34:45 +0100 [thread overview]
Message-ID: <2c94a2af0657f2b95b9337232339ff5ffa643ab5.1612546384.git.andreyknvl@google.com> (raw)
In-Reply-To: <cover.1612546384.git.andreyknvl@google.com>
Mark all static functions in common.c and kasan.h that are used for
hardware tag-based KASAN as inline to avoid unnecessary function calls.
