[LU-4952] osd_declare_write_commit may give wrong offset & size to dmu_tx_hold_write

Tue, 20 May 2014 13:46:16 +0000

in osd_declare_write_commit():

       for (i = 0; i < npages; i++) {
            ......
            dmu_tx_hold_write(oh->ot_tx, obj->oo_db->db_object, offset, size);
            space += osd_count_not_mapped(obj, offset, size);

            offset = lnb->lnb_file_offset;
            size = lnb->len;
       }

they should be lnb[i].lnb_file_offset and lnb[i].len.
