[BLOCK] Clear sg entry before filling in blk_rq_map_sg() The memset() of the sg entry was originally removed, because it could overwrite a chain pointer. But it's quite OK to memset() it when we know it's a valid entry, since it can't contain a chain pointer. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
