From b064b60984fbbe019c8b173b26d1fcd0a4e4df04 Mon Sep 17 00:00:00 2001 From: Weng Xuetian Date: Sat, 14 May 2022 01:11:32 -0700 Subject: Do not clear sibling entries when override. lokid and hikid actually stores the sibling to current node, which should not be cleared when override. This would break the sequence with a common prefix when override another.
