A few thousand randconfig builds later, I actually came across
building this driver.

drivers/scsi/arm/acornscsi.c: In function 'acornscsi_reconnect_finish':
drivers/scsi/arm/acornscsi.c:1779:6: error: implicit declaration of
function 'scsi_cmd_to_tag'; did you mean 'scsi_cmd_to_rq'?
[-Werror=implicit-function-declaration]
scsi_cmd_to_tag(host->SCpnt) == host->scsi.reconnected.tag) {
^~~~~~~~~~~~~~~
scsi_cmd_to_rq
I have no idea what this is meant to do instead, but scsi_cmd_to_tag()
does not appear to be defined in any kernel I can find.
