Subject: [PATCH v2 03/16] tools/include: Add _RET_IP_ and math definitions to kernel.h
Date: Wed, 2 Feb 2022 12:03:02 +0100 [thread overview]
Message-ID: <230fea382cb1e1659cdd52a55201854d38a0a149.1643796665.git.karolinadrobnik@gmail.com> (raw)
In-Reply-To: <cover.1643796665.git.karolinadrobnik@gmail.com>
Add max_t, min_t and clamp functions, together with _RET_IP_
definition, so they can be used in testing.
