Unless Christoph objects, I'll apply this, but I don't understand the situation with 17a51f12cfbd. That commit doesn't check for EINVAL or ENOSPC so I don't know what the connection with this patch is.
I don't think that commit is the culprit.
I know Christoph said he changed something in ahci to treat all errors the same, but I don't know where that is, either.
