Subject: [PATCH v2 0/2] simplify split calculation
Date: Sat,  9 Nov 2024 13:44:08 +0000	[thread overview]
Message-ID: <20241109134410.31792-1-richard.weiyang@gmail.com> (raw)

In version 1 [1], we found current split would result into deficient node.

By discussion, current implementation would lead to jitter problem. Since this
is a rare case in real world, we decide to simplify the split calculation.

Patch 1: simplify split calculation
Patch 2: validate deficient node except for root node

Wei Yang (2):
  maple_tree: simplify split calculation
  maple_tree: only root node could be deficient
