2022-05-04block: allow passing a NULL bdev to bio_alloc_clone/bio_init_cloneChristoph Hellwig
Device mapper wants to allocate a bio before knowing the device it gets send to, so add explicit support for that.

2022-05-02block: ignore RWF_HIPRI hint for sync dioMing Lei
So far bio is marked as REQ_POLLED if RWF_HIPRI/IOCB_HIPRI is passed from userspace sync io interface, then block layer tries to poll until the bio is completed. But the current implementation calls blk_io_schedule() if bio_poll() returns 0, and this way causes io hang or timeout easily. But looks no one reports this kind of issue, which should have been triggered in normal io poll sanity test or blktests block/007 as observed by Changhui, that means it is very likely that no one uses it or no one cares it. Also after io_uring is invented, io poll for sync dio becomes legacy interface. So ignore RWF_HIPRI hint for sync dio.
