Subject: [PATCH] mm: cma: Fix stub for cma_skip_dt_default_reserved_mem()
Date: Wed, 28 Jan 2026 16:28:35 +0000 [thread overview]
Message-ID: <20260128-cma-fix-stubs-v1-1-e07a077d5b33@kernel.org> (raw)
The stub for cma_skip_dt_default_reserved_mem() is not inlined so
triggers build warnings:
In file included from /tmp/next/build/fs/proc/meminfo.c:18:
/tmp/next/build/include/linux/cma.h:68:13: warning: 'cma_skip_dt_default_reserved_mem' defined but not used [-Wunused-function]
68 | static bool cma_skip_dt_default_reserved_mem(void)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
which are fatal with -Werror.
Fixes: 26332ae848f08 ("of: reserved_mem: Allow reserved_mem framework detect "cma=" kernel param")
