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
