353  * Take care of zeroing post-EOF blocks when they might exist.
379 	 * hence be able to correctly determine if we need to run zeroing.  in xfs_file_write_zero_eof()
394 		 * If zeroing is needed and we are currently holding the iolock  in xfs_file_write_zero_eof()
531 	 * iolock.  Also we need to reserve a block each for zeroing the old  in xfs_zoned_write_space_reserve()
734  * to do sub-block zeroing and that requires serialisation against other direct
736  * the unaligned I/O so that we don't get racing block zeroing in the dio layer.
737  * In the case where sub-block zeroing is not required, we can do concurrent
742  * if block allocation or partial block zeroing would be required.  In that case
758 	 * Extending writes need exclusivity because of the sub-block zeroing  in xfs_file_dio_write_unaligned()
1180  *   1.) Hole punch handles partial block zeroing for us.
1370 	 * For zoned file systems, zeroing the first and last block of a hole  in xfs_file_fallocate()
