Not all drivers will need a user interface to turn off hotplug
I would think. At any rate - I would think it'd be better to let
driver writers decide how they want their drivers to behave wrt
hotplug and power instead of forcing a generic policy on everyone.
This patch would provide users of AHCI controllers a way to save
power now, while you work on the grand scheme for polling/turning on off
hotplug via sysfs. It's an interim solution that impacts nobody but
ahci users and is can be easily integrated into whatever solution you
eventually work out.
I like the patch - it seems that it will help a lot of users out near
term in a very positive way while we iterate on the broader solution,
A better patch would enable the _possibility_ of power savings on
non-AHCI chips, and not add a one-off AHCI-specific user interface that
must be supported for years to come.
