has been removed from the -mm tree. Its filename was

Subject: zsmalloc: avoid unused-function warning
Date: Tue, 17 Jan 2023 18:04:59 +0100
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.
