Subject: [PATCH 0/2] Bail out in __stack_depot_save() if the stack_table is not allocated and delete the kmemleak_initialized judgment in set_track_prepare()

patch1 solves the null pointer situation when __stack_depot_save()
is called when the stack_table is not initialized.

patch2 solved there is no call trace for the memory leak which object
is created before the kmemleak_late_init()

Xiaolei Wang (2):
  lib/stackdepot: Bail out in __stack_depot_save() if the stack_table is
    not allocated
  mm/kmemleak: No need to check kmemleak_initialized in
    set_track_prepare()
