Subject: Re: [PATCH] Allow Marvell SATA driver to work with LEDS_TRIGGER_IDE_DISK

I'm testing a revised version of this patch that renames the trigger
to just 'disk' and updates all documentation and default_trigger
definitions to match.  I'm also registering the trigger name
'ide-disk' for now so external tools/scripts/distros won't break while
a depreciation time is chosen.

Once I've verified this behaves on my system, I'm assuming a patch
that touches 25 files should be broken up?  I'm thinking of submitting
in the following chunks:

ledtrig-ide-disk to ledtrig-disk
documentation updates
default-trigger updates
Marvell SATA adjusted to call the trigger

Any objections or comments on this plan of attack?
