In linux kernel since version 5.1 (release Date: 2019-05-05)  
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.
