From: Andrey Konovalov <andreyknvl@google.com>

A few fixes for the stack depot eviction series.

Changes v2->v3:
- Use raw spinlock instead of spinlock to avoid issues on RT kernels.

Changes v1->v2:
- Add Fixes tags.
- Use per-object spinlock for protecting aux stack handles instead of a
  global one.

Andrey Konovalov (4):
  lib/stackdepot: add printk_deferred_enter/exit guards
  kasan: handle concurrent kasan_record_aux_stack calls
  kasan: memset free track in qlink_free
  lib/stackdepot: fix comment in include/linux/stackdepot.h
