From b93ec212bcaccf61313ddbf2527319a7585805ee Mon Sep 17 00:00:00 2001 From: "GONG, Ruiqi" Date: Wed, 16 Aug 2023 11:32:10 +0800 Subject: doc: idmappings: fix an error and rephrase a paragraph If the modified paragraph is referring to the idmapping mentioned in the previous paragraph (i.e. `u0:k10000:r10000`), then it is `u0` that the upper idmapset starts with, not `u1000`. Fix this error and rephrase this paragraph a bit to make this reference more explicit.
