From: Filipe Manana <fdmanana@xxxxxxxx> Test that an incremental send works if we rename some directory inode A and then rename some file inode B to the name inode A had, for the case where the directory inode A is an ancestor of inode B in the parent snapshot. This issue is fixed by the following patch for the linux kernel: "Btrfs: incremental send, fix invalid path for unlink commands" Signed-off-by: Filipe Manana <fdmanana@xxxxxxxx> --- tests/btrfs/145 | 130 ++++++++++++++++++++++++++++++++++++++++++++++++++++ tests/btrfs/145.out | 6 +++ tests/btrfs/group | 1 + 3 files changed, 137 insertions(+) create mode 100755 tests/btrfs/145 create mode 100644 tests/btrfs/145.out diff --git a/tests/btrfs/145 b/tests/btrfs/145 new file mode 100755 index 00000000..ef03292e --- /dev/null +++ b/tests/btrfs/145 @@ -0,0 +1,130 @@ +#! /bin/bash +# FS QA Test No. btrfs/145 +# +# Test that an incremental send works if we rename some directory inode A and +# then rename some file inode B to the name inode A had, for the case where the +# directory inode A is an ancestor of inode B in the parent snapshot. +# +#----------------------------------------------------------------------- +# +# Copyright (C) 2017 SUSE Linux Products GmbH.
