Hi Christoph, Would it be possible to get an IOCB_NO_READ_HOLE flag that causes a read to either fail entirely if there's a hole in the file or to stop at the hole, possibly returning -ENODATA if the hole is at the front of the file? Looking at iomap_dio_iter(), IOMAP_HOLE should be enabled in iomap_iter::iomap.type for this? Is it that simple? David
