Subject: [PATCH v2 0/3] Optimize the fast path of mas_store()
Date: Fri, 9 Jun 2023 20:03:44 +0800 [thread overview]
Message-ID: <20230609120347.63936-1-zhangpeng.00@bytedance.com> (raw)
Add fast paths for mas_wr_append() and mas_wr_slot_store() respectively.
The newly added fast path of mas_wr_append() is used in fork() and how
much it benefits fork() depends on how many VMAs are duplicated.
Changes since v1:
- Revise comment and commit log. [3/3]
- Add test for mas_wr_modify() fast path. [1/3]
v1: https://lore.kernel.org/lkml/20230602075353.5917-1-zhangpeng.00@bytedance.com/
Peng Zhang (3):
maple_tree: add test for mas_wr_modify() fast path
maple_tree: optimize mas_wr_append(), also improve duplicating VMAs
maple_tree: add a fast path case in mas_wr_slot_store()
