The bottom line is that this patch simply wants to trigger an ATA command,

"run this command in background, and discard results" facility requires the
EH.
This is why I was asking if using a workqueue instead of EH might be a
better idea.
EH looks like an overkill here.
A kernel modification might not even be needed.
Have you tried simply issuing READ VERIFY via bsg, and not caring if it
completes? bsg should be able to handle an app submitting a command,
but never checking the 'done' list, right? A simple shell app could execute
write(bsg_fd, ... SCSI READ VERIFY command ...)
exit(0)
to avoid waiting for READ VERIFY command completion, I would hope.
