James & Arjan:
Am I missing something here? It looks like
fastboot: make scsi probes asynchronous
has introduced a bug in the sd probing code. AFAICT, there is now
nothing to prevent do_scan_async() from returning before
sd_probe_async() has run.
Doesn't this mean that there's nothing to prevent sd_remove() from
being called and trying to unregister the disk _before_
sd_probe_async() has managed to register it?
