Subject: mm/kmemleak.c: postpone the disabling of kmemleak early logging
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.
