CONFIG_SLUB_DEBUG: Enable SLUB debugging support

General informations

The Linux kernel configuration item CONFIG_SLUB_DEBUG has multiple definitions:

Enable SLUB debugging support found in mm/Kconfig.debug

The configuration item CONFIG_SLUB_DEBUG:

• prompt: Enable SLUB debugging support
• type: bool
• depends on: ( CONFIG_EXPERT ) && ( CONFIG_SYSFS && ! CONFIG_SLUB_TINY )
• defined in mm/Kconfig.debug
• found in Linux kernels: 5.19, 6.0–6.12

Help text

SLUB has extensive debug support features. Disabling these can result in significant savings in code size. While /sys/kernel/slab will still exist (with SYSFS enabled), it will not provide e.g. cache validation.
