I did not run massive i/o test suite but it now passes basic multiple kernel unpacking in parallel tests (before it didnt' even recognize the partition table). So the patch - at least basically - works. Except that we now have code duplication in kernel. Look at fs/compat.c:compat_do_readv_writev() - it does the same as compat_rw_copy_check_uvector() plus a bit more. I guess it is a good idea to use compat_rw_copy_check_uvector() in compat_do_readv_writev() to build the compat vectors... Thank you for the patch and the fix! /mjt -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
