[PATCH] reiserfs: do not ignore i/io error on readpage

    char * p = NULL;

    int chars;

    int ret ;

    int result ;

    int done = 0 ;

    unsigned long offset ;

		  (loff_t)block * inode->i_sb->s_blocksize + 1, TYPE_ANY, 3);

research:

    if (search_for_position_by_key (inode->i_sb, &key, &path) != POSITION_FOUND) {

    result = search_for_position_by_key (inode->i_sb, &key, &path) ;

    if (result != POSITION_FOUND) {

	pathrelse (&path);

        if (p)

            kunmap(bh_result->b_page) ;

	if (result == IO_ERROR)

	    return -EIO;

	// We do not return -ENOENT if there is a hole but page is uptodate, because it means

	// That there is some MMAPED data associated with it that is yet to be written to disk.

	if ((args & GET_BLOCK_NO_HOLE) && !PageUptodate(bh_result->b_page) ) {

	// update key to look for the next piece

	set_cpu_key_k_offset (&key, cpu_key_k_offset (&key) + chars);

	if (search_for_position_by_key (inode->i_sb, &key, &path) != POSITION_FOUND)

	    // we read something from tail, even if now we got IO_ERROR

	result = search_for_position_by_key (inode->i_sb, &key, &path);

	if (result != POSITION_FOUND)

	    // i/o error most likely

	    break;

	bh = get_last_bh (&path);

	ih = get_ih (&path);

finished:

    pathrelse (&path);

    if (result == IO_ERROR)

	return -EIO;

    /* this buffer has valid data, but isn't valid for io.  mapping it to

     * block #0 tells the rest of reiserfs it just has a tail in it
