A little more explanation might be helpful. It looks to me that you get this issue when you have in-flight I/O to a device we've been notified has gone (because you NULL out lldd_dev in the removal notification routine). In which case, don't we have other races where this can happen, like in mvs_I_T_nexus_reset()?
