Subject: [PATCH v3 0/5] refine storing NULL
Date: Fri, 18 Oct 2024 02:39:38 +0000	[thread overview]
Message-ID: <20241018023943.13860-1-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_store_root() to improve memory efficiency and remove                                                                                                                                     
possible consecutive NULL slot.                                                                                                                                                                              
                                                                                                                                                                                                             
Patch 5 adds a test for storing NULL.

v3:
  patch 4 move the change into mas_store_root()
  patch 5 move test into lib/test_maple_tree.c

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_store_root() on storing NULL
  maple_tree: add a test checking storing null
