Subject: [PATCH 9/8] memblock tests: add stubs required for free_reserved_area()
Date: Wed, 18 Mar 2026 22:52:21 +0200 [thread overview]
Message-ID: <20260318205221.1402161-1-rppt@kernel.org> (raw)
In-Reply-To: <20260318105827.1358927-1-rppt@kernel.org>
From: "Mike Rapoport (Microsoft)" <rppt@kernel•org>
After moving free_reserved_area() function to mm/memblock.c memblock
tests lack stubs for several functions and macros this function calls.
Add them.
