From c997d683d952d8c927922ea0ab4d33a01c8efc2c Mon Sep 17 00:00:00 2001 From: Chengming Zhou Date: Sat, 24 Feb 2024 13:53:15 +0000 Subject: [PATCH] vfs: remove SLAB_MEM_SPREAD flag usage The SLAB_MEM_SPREAD flag used to be implemented in SLAB, which was removed as of v6.8-rc1 (see [1]), so it became a dead flag since the commit 16a1d968358a ("mm/slab: remove mm/slab.c and slab_def.h"). And the series[1] went on to mark it obsolete explicitly to avoid confusion for users. Here we can just remove all its users, which has no any functional change.
