Subject: [PATCH 0/6] blk-mq: initialize pdu of flush req explicitly

Hi,

This patchset introduces init_flush_rq and its pair callback to
initialize pdu of flush request explicitly, instead of using
copying from request which is inefficient and buggy, and implements
them in virtio-blk and scsi-lib.
