[PATCH] USB Storage: close a race condition in disconnect near queuecommand
This patch started life as as534, and has been re-diffed against the latest
tree.
usb-storage has a small loophole, a window between the time queuecommand
accepts a new command and the time the control thread starts to execute
it. If disconnect is called during that window, the driver won't cancel
the pending command -- we've been relying on the SCSI core to cancel it
for us during host removal. But it's better for usb-storage to cancel
it; this avoids races and reduces reliance on the SCSI core.
Fortunately cancelling these commands is easy to do; the key is to do it
_before_ calling scsi_remove_host.
