   7 # Regression test for the btrfs incremental send feature, where the kernel
   8 # would incorrectly consider a range of a file as a hole and send a stream
   9 # of 0 bytes to the destination (send stream) that would overwrite the
  10 # corresponding file region.
  11 #
  12 # This issue is fixed by the following linux kernel btrfs patch:
  13 #
  14 #   Btrfs: send, fix data corruption due to incorrect hole detection
