Can we also consider to disable fair tag sharing by default for the
driver that total driver tags is less than a threshold?
I don't want to do this because such a change could disable fair tag
sharing for drivers that support both SSDs and hard disks being associated
with a single SCSI host.
Ok, then is this possible to add a sysfs entry to disable/enable fair
tag sharing manually?
Thanks,
