    [BLOCK] blk_rq_map_sg: force clear termination bit · 7aeacf98
    Jens Axboe authored
    Since blk_rq_map_sg() sets the termination bit at the end of the sg
    table, we could see it prematurely on the next mapping unless we
    force drivers to do a full sg_init_table() prior to each mapping. So
    force clear the termination bit to avoid having to put that clear in
    the driver for every mapping.
