From 323b0899adfb927de2233514960a95fb726765ab Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 12 Aug 2024 14:19:23 -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.
