From: Arnd Bergmann <arnd@xxxxxxxx> obj_allocated() can be called from two places that are each inside of an #ifdef. When both are disabled, the compiler warns: mm/zsmalloc.c:900:13: error: 'obj_allocated' defined but not used [-Werror=unused-function] Rather than trying to figure out the correct #ifdef, mark the trivial function as 'inline', which implies __maybe_unused and shuts up the warning.
