As long as we don't crash the drive or AHCI controller

Yes, but they'll also send an ACPI interrupt even if the SATA host
controller doesn't - it's part of the spec for bays.
Does the spec mandate that the ACPI interrupt shouldn't depend on SATA
phy status? I

I don't think the end result will vary in any significant way. My
biggest argument for sw implementation is it can be used for other

What I had in mind when I created the new port operation enable_pm
was that
ata_scsi_pass_thru() is not executed at ioctl submission time (block
queue submission time), but rather immediately before it is issued to
the drive. At that point you know the bus is idle, all other commands
have finished executing, and dev-multi_count is fresh not stale. The

Excluding the corner case of an Expresscard SATA controller (where I
suspect you'd want different policy), I doubt there are any cases where
you have a laptop with hotplug capabilities without it being implemented
as an ACPI bay.
