Filipe Manana 9edaf22811 btrfs: test cloning of zero length ranges
Test cloning a file range with a length of zero into a destination offset
greater than zero.

This made btrfs create an extent state record with a start offset greater than
the end offset, resulting in chaos such as an infinite loop when evicting an
inode.

This issue was fixed by the following linux kernel patch:
