From 5fda0976e88dd4addc401af6b2ab53b2842e47a6 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Sun, 8 Nov 2020 16:32:43 -0800 Subject: [PATCH] xfs: set the unwritten bit in rmap lookup flags in xchk_bmap_get_rmapextents [ Upstream commit 5dda3897fd90783358c4c6115ef86047d8c8f503 ] When the bmbt scrubber is looking up rmap extents, we need to set the extent flags from the bmbt record fully. This will matter once we fix the rmap btree comparison functions to check those flags correctly. Fixes: d852657ccfc0 ("xfs: cross-reference reverse-mapping btree") Signed-off-by: Darrick J.
