Hello, It looks like sata_mv triggers BUG_ON() when a command it doesn't know about is issued and discard support makes it happen. Can you guys take a look? And please update it such that it doesn't trigger BUG_ON() only because an unknown command is issued. That's way too dangerous. If void return from qc_prep is a problem, just move the whole qc_prep into qc_issue, the distinction is pretty arbitrary anyway.
