This series of patches makes possible to do direct block IO with integrity payload using io uring kernel interface. Userspace app can utilize new READV_PI/WRITEV_PI operation with a new fields in sqe struct (pi_addr/pi_len) to provide iovec's with integrity data. Changes since v1: - switch to using separated io uring op codes and additional sqe fields (instead of sqe flag) - ability to process multiple iovecs - use unused space in bio to pin user pages Alexander V.
