Subject: [PATCH v3 0/3] simplify split calculation
Date: Wed, 13 Nov 2024 03:16:13 +0000 [thread overview]
Message-ID: <20241113031616.10530-1-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: add a test case to check deficient node
Patch 3: validate deficient node except for root node

maple_tree: simplify split calculation
maple_tree: add a test check deficient node
maple_tree: only root node could be deficient
