From 5eef46358fae1a6018d9f886a3ecd30e843728dd Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Sun, 6 Nov 2022 17:03:22 -0800 Subject: xfs: teach scrub to flag non-extents format cow forks CoW forks only exist in memory, which means that they can only ever have an incore extent tree. Hence they must always be FMT_EXTENTS, so check this when we're scrubbing them. Signed-off-by: Darrick J.
