   2 # FS QA Test No. btrfs/046
   3 #
   4 # Regression test for the btrfs incremental send feature, where the kernel
   5 # would incorrectly consider a range of a file as a hole and send a stream
   6 # of 0 bytes to the destination (send stream) that would overwrite the
   7 # corresponding file region.
   8 #
   9 # This issue is fixed by the following linux kernel btrfs patch:
  10 #
  11 #   Btrfs: send, fix data corruption due to incorrect hole detection
