# 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.
