From ea99122b18ca6cf902417e1acbc19a197f662299 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Sun, 3 Nov 2024 20:19:31 -0800 Subject: [PATCH] xfs: mask off the rtbitmap and summary inodes when metadir in use Set the rtbitmap and summary file inumbers to NULLFSINO in the superblock and make sure they're zeroed whenever we write the superblock to disk, to mimic mkfs behavior.
