Subject: [PATCH 0/2] zsmalloc: small compaction improvements
Date: Fri, 23 Jun 2023 13:40:00 +0900 [thread overview]
Message-ID: <20230623044016.366793-1-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.
Sergey Senozhatsky (2):
zsmalloc: do not scan for allocated objects in empty zspage
zsmalloc: move migration destination zspage inuse check
