Subject: [PATCH v3 0/3] followups to debug_pagealloc improvements through page_owner
Date: Mon, 7 Oct 2019 11:18:05 +0200 [thread overview]
Message-ID: <20191007091808.7096-1-vbabka@suse.cz> (raw)
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).
