Test that both a full and incremental btrfs send operation preserves file holes. This used to fail when the filesystem had the NO_HOLES feature enabled, that is, when the test is run with MKFS_OPTIONS="-O no-holes". This is fixed by the following patch for the linux kernel: "Btrfs: incremental send, fix unnecessary hole writes for sparse files" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Eryu Guan <eguan@redhat.com> Signed-off-by: Eryu Guan <eguan@redhat.com>
