From 2a19be61a65157b9c6c25e831392cdefbd0a8940 Mon Sep 17 00:00:00 2001 From: Vlastimil Babka Date: Mon, 2 Oct 2023 15:43:03 +0200 Subject: mm/slab: remove CONFIG_SLAB from all Kconfig and Makefile Remove CONFIG_SLAB, CONFIG_DEBUG_SLAB, CONFIG_SLAB_DEPRECATED and everything in Kconfig files and mm/Makefile that depends on those. Since SLUB is the only remaining allocator, remove the allocator choice, make CONFIG_SLUB a "def_bool y" for now and remove all explicit dependencies on SLUB or SLAB as it's now always enabled. Make every option's verbose name and description refer to "the slab allocator" without refering to the specific implementation. Do not rename the CONFIG_ option names yet. Everything under #ifdef CONFIG_SLAB, and mm/slab.c is now dead code, all code under #ifdef CONFIG_SLUB is now always compiled.
