btrfs: test incremental send with compression and extent cloning
Test that an incremental send/receive operation will not fail when the
destination filesystem has compression enabled and the source filesystem
has a 4K extent at a file offset 0 that is not compressed and that is
shared.
This currently fails on btrfs and is fixed by the following patch for the
linux kernel:
"Btrfs: incremental send, fix emission of invalid clone operations"
