Hyeoncheol Jeong <hyenc.jeong@samsung.com> says: 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. Patch 1 is a preparatory cleanup that switches the BSG query descriptor length to unsigned types. Patch 2 adds the aggregated read support. v3: https://lore.kernel.org/linux-scsi/20260724030812epcms2p4eb2c77cb4dcd5fd51ca9c3eaa5ea4bfa@epcms2p4/ v2: https://lore.kernel.org/linux-scsi/20260722084819epcms2p49c27fce999e821385f7b5d7ea5a02868@epcms2p4/ Link: https://patch.msgid.link/20260728092208epcms2p881b17276fb41c006a4229c1d073b4ad0@epcms2p8 Signed-off-by: Martin K.
