The answers that you constantly ignore is that the patch in question does not add any new ways to corrupt memory which are not possible using _upstream_ uio_pci_generic device, so the fact that uio_pci_generic can corrupt memory cannot be used as a reason to not apply patches that do not corrupt any memory. You seams to be constantly arguing that uio_pci_generic is not suitable for upstream. -- Gleb. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
