4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Alexander Kappner <agk@xxxxxxxxxxx> commit ca7d9515d0e6825351ce106066cea1f60e40b1c8 upstream. The "G-Drive" (sold by G-Technology) external USB 3.0 drive hangs on write access under UAS and usb-storage: [ 136.079121] sd 15:0:0:0: [sdi] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 136.079144] sd 15:0:0:0: [sdi] tag#0 Sense Key : Illegal Request [current] [ 136.079152] sd 15:0:0:0: [sdi] tag#0 Add. Sense: Invalid field in cdb [ 136.079176] sd 15:0:0:0: [sdi] tag#0 CDB: Write(16) 8a 08 00 00 00 00 00 00 00 00 00 00 00 08 00 00 [ 136.079180] print_req_error: critical target error, dev sdi, sector 0 [ 136.079183] Buffer I/O error on dev sdi, logical block 0, lost sync page write [ 136.173148] EXT4-fs (sdi): mounted filesystem with ordered data mode.

The proposed patch adds compatibility quirks. Because the drive requires two quirks (one to work with UAS, and another to work with usb-storage), adding this under unusual_devs.h and not just unusual_uas.h so kernels compiled without UAS receive the quirk. With the patch, the drive works reliably on UAS and usb- storage. (tested on NEC Corporation uPD720200 USB 3.0 host controller).
