   -p, --punch-hole
          Deallocates  space  (i.e.,  creates  a hole) in the byte range starting at offset and continuing for length bytes.  Within the specified
          range, partial filesystem blocks are zeroed, and whole filesystem blocks are removed from the file.  After a successful call, subsequent
          reads  from  this  range will return zeroes.  This option may not be specified at the same time as  the --zero-range option.  Also, when
          using this option, --keep-size is implied.

          Supported for XFS (since Linux 2.6.38), ext4 (since Linux 3.0), Btrfs (since Linux 3.7) and tmpfs (since Linux 3.5).
