If you are talking about SATA -- incorrect.
The patch deals with policy, and the user MUST have the ability to
control this stuff. Otherwise you create a situation where the user
might be denied hotplug use in valid cases, or similar negative situations.
The policy isn't however complicated. Tejun added the stuff for forcing
cable type and mode on setup and has therefore written all the per device
setup code we might need. Alternatively a single
foo=1/0
option has been fine for acpi and will do fine for this. Total additional
cost - 1 line.
The key requirement is per-port control. Ideally via hdparm or another
userspace tool, but kernel command line (module options) or sysfs would
be just fine too. And agreed, the minimal you need is simply 1/0 for
the port's policy.
