Yes, I'm fine. Send it for -mm now I'd also like to ship it against 2.6.12 for wider testing. And the open question is: we (actually you) tested the whole patchset; is there any known bug (for skas0) fixed only by patches we are leaving out? -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
