    mm/slub: avoid recursive loop with kmemleak · 3b89ec41
    Kees Cook authored
    The system will immediate fill up stack and crash when both
    CONFIG_DEBUG_KMEMLEAK and CONFIG_MEM_ALLOC_PROFILING are enabled.  Avoid
    allocation tagging of kmemleak caches, otherwise recursive allocation
    tracking occurs.
