Subject: [PATCH v3 0/2] mm: batch mm counter updating in filemap_map_pages()
Date: Fri, 12 Apr 2024 14:47:49 +0800 [thread overview]
Message-ID: <20240412064751.119015-1-wangkefeng.wang@huawei.com> (raw)
Let's batch mm counter updating to accelerate filemap_map_pages().
v2:
- estimate folio type from caller and no need to return from
set_pte_range()
- use unsigned long for rss
v3:
- make is_cow to bool in patch1 and fix null folio in patch2
- retest, improvement same with v1

mm: move mm counter updating out of set_pte_range()
mm: filemap: batch mm counter updating in filemap_map_pages()
