We're interested in this patch, is there an updated version (I'd rather not
try to fix the deprecated timer function myself), we can try? We have a
very easy way to reproduce this problem in Real Life (VMs connecting to a
scst target server) so if nothing else we can provide some testing. :)

this patch adds handling of BUSY status reponse from an iSCSI target.
Currently, we fail with -EIO in case of SCSI_STATUS_BUSY while the
obvious reaction would be to retry the operation after some time.
The retry time is randomly choosen from a range with exponential
growth increasing with each

This is a pretty fast growth.

I know, I wanted to end up with a total retry period of approx. 10 seconds
before failing.

Yes, exactly (except that log(1) is zero, and was only needed in your
case
