NVMe passthru takes a single buffer pointer.
This enables using multiple buffers for passthru, similiar to
readv/writev.
First patch is prep, while second one adds vectored-io abililty to
NVME_IOCTL_IO64_CMD.
Kanchan Joshi (2):
block: introduce and export blk_rq_map_user_vec
nvme: add vectored-io support for user passthru
