Subject: [PATCH v2] mm/slub: fix help comment of SLUB_DEBUG
Date: Tue, 14 Mar 2023 15:16:01 +0800 [thread overview]
Message-ID: <20230314071601.343817-1-vernon2gm@gmail.com> (raw)
Since commit ab4d5ed5eeda ("slub: Enable sysfs support for
!CONFIG_SLUB_DEBUG"), disabling SLUB_DEBUG also disables
SLUB sysfs support that is not true anymore, so fix it correctly.

SLUB has extensive debug support features. Disabling these can
- result in significant savings in code size. This also disables
- SLUB sysfs support. /sys/slab will not exist and there will be
- no support for cache validation etc.
+ result in significant savings in code size, the /sys/kernel/slab
+ will exist but will not provide e.g. cache validation.
