From 01c69ef56dfa760651f86a34b243d0ef1d8827b8 Mon Sep 17 00:00:00 2001 From: "Vlastimil Babka (SUSE)" Date: Fri, 3 Jul 2026 12:31:56 +0000 Subject: mm: remove the __GFP_NO_OBJ_EXT flag All users of the flag are converted to SLAB_ALLOC_NO_RECURSE or ALLOC_NO_CODETAG (from __GFP_NO_CODETAG which reused the NO_OBJ_EXT bit). Free up the flag bit. [Rebased onto __GFP_NO_CODETAG removal] Link: https://lore.kernel.org/20260703-alloc-trylock-v5-16-c87b714e19d3@google.com Signed-off-by: Vlastimil Babka (SUSE) Signed-off-by: Brendan Jackman Acked-by: Hao Ge Signed-off-by: Andrew Morton --- tools/include/linux/gfp_types.h | 7 ------- 1 file changed, 7 deletions(-) (limited to 'tools/include/linux') diff --git a/tools/include/linux/gfp_types.h b/tools/include/linux/gfp_types.h index 54ca0c88bab6..da47aa089f01 100644 --- a/tools/include/linux/gfp_types.h +++ b/tools/include/linux/gfp_types.h @@ -55,7 +55,6 @@ enum { #ifdef CONFIG_LOCKDEP ___GFP_NOLOCKDEP_BIT, #endif - ___GFP_NO_OBJ_EXT_BIT, ___GFP_LAST_BIT }; @@ -96,7 +95,6 @@ enum { #else #define ___GFP_NOLOCKDEP 0 #endif -#define ___GFP_NO_OBJ_EXT BIT(___GFP_NO_OBJ_EXT_BIT) /* * Physical address zone modifiers (see linux/mmzone.h - low four bits) @@ -137,17 +135,12 @@ enum { * node with no fallbacks or placement policy enforcements. * * %__GFP_ACCOUNT causes the allocation to be accounted to kmemcg. - * - * %__GFP_NO_OBJ_EXT causes slab allocation to have no object extension. - * mark_obj_codetag_empty() should be called upon freeing for objects allocated - * with this flag to indicate that their NULL tags are expected and normal. */ #define __GFP_RECLAIMABLE ((__force gfp_t)___GFP_RECLAIMABLE) #define __GFP_WRITE ((__force gfp_t)___GFP_WRITE) #define __GFP_HARDWALL ((__force gfp_t)___GFP_HARDWALL) #define __GFP_THISNODE ((__force gfp_t)___GFP_THISNODE) #define __GFP_ACCOUNT ((__force gfp_t)___GFP_ACCOUNT) -#define __GFP_NO_OBJ_EXT ((__force gfp_t)___GFP_NO_OBJ_EXT) /** * DOC: Watermark modifiers -- cgit v1.2.3
