From: Masahiro Yamada <masahiroy@xxxxxxxxxx>
With CONFIG_BLK_DEV_RNBD_CLIENT=m and CONFIG_BLK_DEV_RNBD_SERVER=y
(or vice versa), rnbd-common.o is linked to a module and also to
vmlinux even though CFLAGS are different between builtins and modules.
This is the same situation as fixed by commit 637a642f5ca5 ("zstd:
Fixing mixed module-builtin objects").
Turn rnbd_access_mode_str() into an inline function.
Why inline? All you should need is "static" to keep these internal to
each compilation unit. Inline also bloats the object files when the
function is called from multiple places. Let the compiler decide when
to inline.
