I should have caught this issue when Yinghai's patch went in: the right way to silence a warning about not checking a return value isn't to simply assign it to something, you really should *do* something as well, at least some debug output would be nice, but ideally handling the error in a sane way. -- Jesse Barnes, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
