Test that an incremental send receive does not issue clone operations
that attempt to clone the last block of a file, with a size not aligned to
the filesystem's sector size, into the middle of some other file. Such
clone request causes the receiver to fail (with EINVAL), for kernels that
include commit ac765f83f1397646 ("Btrfs: fix data corruption due to
cloning of eof block"), or cause silent data corruption for older kernels.
This test is motived by a recent regression introduced in kernel 5.2-rc1,
commit 040ee6120cb6706 ("Btrfs: send, improve clone range"), and the
following patch fixes it:
"Btrfs: incremental send, fix emission of invalid clone perations"
