Following the discussions on v2 of this patch(set) [1], this series takes slightly different approach: - it implements its own simple memory pool that does not rely on the slab allocator - drops the early log buffer logic entirely since it can now allocate metadata from the memory pool directly before kmemleak is fully initialised - CONFIG_DEBUG_KMEMLEAK_EARLY_LOG_SIZE option is renamed to CONFIG_DEBUG_KMEMLEAK_MEM_POOL_SIZE - moves the kmemleak_init() call earlier (mm_init()) - to avoid a separate memory pool for struct scan_area, it makes the tool robust when such allocations fail as scan areas are rather an optimisation [1] http://lkml.kernel.org/r/20190727132334.9184-1-catalin.marinas@xxxxxxx Catalin Marinas (3): mm: kmemleak: Make the tool tolerant to struct scan_area allocation failures mm: kmemleak: Simple memory allocation pool for kmemleak objects mm: kmemleak: Use the memory pool for early allocations init/main.c | 2 +- lib/Kconfig.debug | 11 +- mm/kmemleak.c | 325 ++++++++++++---------------------------------- 3 files changed, 91 insertions(+), 247 deletions(-)
