From 89ea026b8c2f5c167b5edfb549617f304b9fe395 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 15 Aug 2024 11:58:29 -0700 Subject: [PATCH] xfs_repair: allow CoW staging extents in the realtime rmap records Don't flag the rt rmap btree as having errors if there are CoW staging extent records in it and the filesystem supports. As far as reporting leftover staging extents, we'll report them when we scan the rt refcount btree, in a future patch. Signed-off-by: Darrick J.
