From ce8475b6a4e547fcea60410a8385d80988e12c7e Mon Sep 17 00:00:00 2001 From: Miaohe Lin <linmiaohe@huawei.com> Date: Wed, 30 Jun 2021 18:53:01 -0700 Subject: [PATCH] mm/zsmalloc.c: remove confusing code in obj_free() Patch series "Cleanup for zsmalloc". This series contains cleanups to remove confusing code in obj_free(), combine two atomic ops and improve readability for async_free_zspage(). More details can be found in the respective changelogs. This patch (of 2): OBJ_ALLOCATED_TAG is only set for handle to indicate allocated object. It's irrelevant with obj. So remove this misleading code to improve readability.
