Aside from one minor requested change, this patchset is ACK'd, but with
a few comments and worries noted.
Once this goes in we need to move all the drivers over as soon as
possible, and get them all re-tested.
I will be a lot of work. As new EH uses features unused before, it
sometimes exposes new hardware problems (things like sata_sil24 port
wide IRQ plugging doesn't really work). Those problems take time to
diagnose and work around. Also, different strains of a controller might
show different symptoms. So, we need a lot of testing.
I agree that drivers should be converted ASAP but honestly don't know
how fast those can be done; however, libata will continue to work with
all the old-EH drivers as well as before, so we have some headroom.
