Hi all, this is a rebased of the tests dave sent 5 years ago for the xfs post-EOF block freeing. Without the patches here: https://lore.kernel.org/linux-xfs/20240623053532.857496-1-hch@xxxxxx/ all of the new tests will fail for the default configuration. Changes since v1: - fix _scratch_mkfs output redirection - add _cleanup handlers
