Regression test for the btrfs incremental send feature, where the kernel
would incorrectly consider a range of a file as a hole and send a stream
of 0 bytes to the destination (send stream) that would overwrite the
corresponding file region.

This issue is fixed by the following linux kernel btrfs patch:

   Btrfs: send, fix data corruption due to incorrect hole detection
   (https://patchwork.kernel.org/patch/3910081/)
