This test is motivated by a bug found in btrfs, which is fixed by the linux kernel patch titled: "Btrfs: fix log replay failure after unlink and link combination" Signed-off-by: Filipe Manana Reviewed-by: Eryu Guan Signed-off-by: Eryu Guan --- diff --git a/tests/generic/480 b/tests/generic/480 new file mode 100755 index 00000000..a287684b --- /dev/null +++ b/tests/generic/480 @@ -0,0 +1,83 @@ +#! /bin/bash +# FSQA Test No. 480 +# +# Test that if we have a file with two hard links in the same parent directory, +# then remove of the links, create a new file in the same parent directory and +# with the name of the link removed, fsync the new file and have a power loss, +# mounting the filesystem succeeds. +# +#----------------------------------------------------------------------- +# +# Copyright (C) 2018 SUSE Linux Products GmbH.
