From 412795cfdde0f33c4f9ee76990c61d53c0f504a7 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Mon, 15 Mar 2021 15:18:24 +0100 Subject: [PATCH] btrfs: fix slab cache flags for free space tree bitmap commit 34e49994d0dcdb2d31d4d2908d04f4e9ce57e4d7 upstream. The free space tree bitmap slab cache is created with SLAB_RED_ZONE but that's a debugging flag and not always enabled. Also the other slabs are created with at least SLAB_MEM_SPREAD that we want as well to average the memory placement cost.
