Subject: [PATCH v3 0/2] kasan: reset tag when accessing invalid metadata

With hardware tag-based kasan enabled, we reset the tag
when we access metadata to avoid from false alarm.

Changes since v3:
 - Remove inappropriate suggested-by

Changes since v2:
 - Refine the commit message in detail.
 - Thanks Andrey's explanation about false alarm
   of kmemleak.

Kuan-Ying Lee (2):
  kasan, kmemleak: reset tags when scanning block
  kasan, slub: reset tag when printing address
