Subject: [PATCH v3 0/2] mm/kmemleak: use object_cache instead of kmemleak_initialized

use object_cache instead of kmemleak_initialized to check in
set_track_prepare(), so that memory leaks after kmemleak_init()
can be recorded and Rename kmemleak_initialized to
kmemleak_late_initialized

unreferenced object 0xc674ca80 (size 64):
 comm "swapper/0", pid 1, jiffies 4294938337 (age 204.880s)
 hex dump (first 32 bytes):
  80 55 75 c6 80 54 75 c6 00 55 75 c6 80 52 75 c6 .Uu..Tu..Uu..Ru.
  00 53 75 c6 00 00 00 00 00 00 00 00 00 00 00 00 .Su..........

Change in V3:
The comment in set_track_prepare() in patch1 is updated to

  	/*
	 * Use object_cache to determine whether kmemleak_init() has
	 * been invoked.stack_depot_early_init() is called before
	 * kmemleak_init() in mm_core_init().
	 */

Updated the commit log in patch2, Rename kmemleak_initialized to
kmemleak_late_initialized indicates that kmemleak_late_init() is complete

Change in V2:
Delete patch1 in v1 version, change patch2, use object_cache instead of
kmemleak_initialized to check in set_track_prepare(), so that memory leak
after kmemleak_init() can be recorded, and rename kmemleak_initialized to
kmemleak_late_initialized

  mm/kmemleak: use object_cache instead of kmemleak_initialized to check
    in set_track_prepare()
  Rename kmemleak_initialized to kmemleak_late_initialized
