CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE: Kmemleak memory pool size

General informations

The Linux kernel configuration item CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE has multiple definitions:

Kmemleak memory pool size found in mm/Kconfig.debug

The configuration item CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE:

• prompt: Kmemleak memory pool size
• type: int
• depends on: CONFIG_DEBUG_KMEMLEAK
• defined in mm/Kconfig.debug
• found in Linux kernels: 6.3–6.8, 6.9-rc+HEAD

Help text

Kmemleak must track all the memory allocations to avoid reporting false positives. Since memory may be allocated or freed before kmemleak is fully initialised, use a static pool of metadata objects to track such callbacks. After kmemleak is fully initialised, this memory pool acts as an emergency one if slab allocations fail.
