Currently named "perf"

Suggested names:

• disk
• io

Please add a vote or another suggestion, We'll rename it in a few days.

My vote would be logical_disk, despite the length :) If we will expose the PhysicalDisk family some time (which I think would be useful) , it will need to be possible to distinguish them.

[martinlindhe]

Makes sense. I have no objections :-)

[martinlindhe]

Do you mind doing the rename, if you are already knee-deep in the code? If not, I'll do it on monday or so. Also the perf.go should be renamed to logical_disk.go, and maybe refactor the subsystem name into a const.

[carlpett]

Sure! Good point about the const as well.

(hopefully resolved in #5)
