[PATCH] xfstests: add regression test for btrfs incremental send
Test for a btrfs incremental send issue where we end up sending a wrong section of data from a file extent if the corresponding file extent is compressed and the respective file extent item has a non zero data offset. Fixed by the following linux kernel btrfs patch: Btrfs: use right clone root offset for compressed extents Signed-off-by: Filipe David Borba Manana <fdmanana@gmail.com> --- tests/btrfs/040 | 103 +++++++++++++++++++++++++++++++++++++++++++++++++++ tests/btrfs/040.out | 1 + tests/btrfs/group | 1 + 3 files changed, 105 insertions(+) create mode 100755 tests/btrfs/040 create mode 100644 tests/btrfs/040.out diff --git a/tests/btrfs/040 b/tests/btrfs/040 new file mode 100755 index 0000000..c1f3d13 --- /dev/null +++ b/tests/btrfs/040 @@ -0,0 +1,103 @@ +#! /bin/bash +# FS QA Test No. btrfs/040 +# +# Test for a btrfs incremental send issue where we end up sending a +# wrong section of data from a file extent if the corresponding file +# extent is compressed and the respective file extent item has a non +# zero data offset. +# +# Fixed by the following linux kernel btrfs patch: +# +# Btrfs: use right clone root offset for compressed extents +# +#----------------------------------------------------------------------- +# Copyright (c) 2014 Filipe Manana.
