Hyeoncheol,

> UFS 5.0 / JEDEC 220H introduces the AGGREGATED READ query opcode
> (0x9), which retrieves an aggregated data packet bundling multiple
> Descriptors, Attributes and Flags in a single QUERY RESPONSE UPIU.
> Such a packet can be far larger than a single descriptor, so the
> reserved (device management) tag gets a dedicated UCD with an enlarged
> response area.

Applied to 7.3/scsi-staging, thanks!
