Subject[PATCH v3 0/3] followups to debug_pagealloc improvements through page_owner
Date
Changes since v2 [3]:

- Qian Cai suggested that the extra boot option and page_ext ops is unnecessary
for a debugging option, unless somebody really complains about the overhead,
with numbers. So patch 2 is greatly simplified.

These are followups to [1] which made it to Linus meanwhile. Patches 1 and 3
are based on Kirill's review, patch 2 on KASAN request [2]. It would be nice
if all of this made it to 5.4 with [1] already there (or at least Patch 1).
