[PATCH 0/2] Fix invalid wait context of set_track_prepare()

[Liu Shixin]

Geert reported an invalid wait context[1] which is resulted by moving
set_track_prepare() inside kmemleak_lock. This is not allowed because
in RT mode, the spinlocks can be preempted but raw_spinlocks can not,
so it is not allowd to acquire spinlocks while holding raw_spinlocks.
The second patch fix same problem in kmemleak_update_trace().
