Subject: [PATCH v2 0/5] refine storing NULL
Date: Thu, 17 Oct 2024 13:46:02 +0000	[thread overview]
Message-ID: <20241017134607.30206-1-richard.weiyang@gmail.com> (raw)

The original thread[1] thoughts it is a problem in mas_new_root(). But after
discussion, this should be an improvement on storing NULL.

Patch 1/2 preparation for refine.

Patch 3 remove redundant check in mas_new_root().

Patch 4 refine mas_root_expand() to improve memory efficiency and remove
possible consecutive NULL slot.

Patch 5 adds a test for storing NULL.

Wei Yang (5):
  maple_tree: print empty for an empty tree on mt_dump()
  maple_tree: the return value of mas_root_expand() is not used
  maple_tree: not necessary to check index/last again
  maple_tree: refine mas_root_expand() on storing NULL
  maple_tree: add a test checking storing null
