As with with the previous patch the BUG_ON/crash is fixed and as before dmesg only says this now: [ 17.884175] sd 0:0:1:0: [sdb] tag#0 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [ 17.884180] sd 0:0:1:0: [sdb] tag#0 Sense Key : Illegal Request [current] [ 17.884185] sd 0:0:1:0: [sdb] tag#0 Add.

It's hard to say if this is desirable given that the underlying devices switch to saying they don't support discard but perhaps that's part of a different discussion.
