Subject: [PATCHv2 0/3] zsmalloc: small compaction improvements
Date: Sat, 24 Jun 2023 14:12:13 +0900 [thread overview]
Message-ID: <20230624053120.643409-1-senozhatsky@chromium.org> (raw)
Hi,
A tiny series that can reduce the number of
find_alloced_obj() invocations (which perform a linear
scan of sub-page) during compaction. Inspired by Alexey
Romanov's findings.
v2:
-- picked up a patch from Minchan
Minchan Kim (1):
zsmalloc: remove zs_compact_control
Sergey Senozhatsky (2):
zsmalloc: do not scan for allocated objects in empty zspage
zsmalloc: move migration destination zspage inuse check
