Currently, kmemleak_early_log is disabled 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 moves the kmemleak_early_log disabling further down and at the same time with full kmemleak enabling.
