This test verifies that after an incremental btrfs send the replicated file has the same exact hole and data structure as in the origin filesystem. This didn't use to be the case before the send stream version 2 - holes were sent as write operations of 0 valued bytes instead of punching holes with the fallocate system call, and pre-allocated extents were sent as well as write operations of 0 valued bytes instead of intructions for the receiver to use the fallocate system call. It also checks that prealloc extents that lie beyond the file's size are replicated by an incremental send.
