Oh, yeah, things like that can definitely be changed, but I think it
would still need to be piped through EH.  That's how the queue gets
quiesced for those special operations and resume is basically probing,
so it doesn't make much sense to split them.  Please let me know how
it should work from power management POV and I'll be happy to convert
libata to fit the new behavior.

Thanks.
