Commit 8910ae896c8c (kmemleak: change some global variables to int), in addition to the atomic -> int conversion, moved the kmemleak_early_log disabling at the beginning of the kmemleak_init() function, before the full kmemleak tracing is actually enabled. In this small window, kmem_cache_create() is called by kmemleak which triggers additional memory allocation that are not traced. This patch restores the original logic with kmemleak_early_log disabling when kmemleak is fully functional.
