yes, though by that point I had thought it was a done deal and so was mostly complaining about it with regard to another issue. I usually don't hang out on the ARM lists, but perf-event related ones, which was why I was primarily discussing the issue with Will Deacon in that case. > One thing I still can't get my head around though is...

Had it been sitting somewhere else? That's a good question. Someone definitely had told me that is was going to happen earlier, but I can't remember where now. Definitely someone with enough authority that I thought it wasn't worth the trouble complaining (I already seemingly have half the perf_event people annoyed with me on any given day, the last thing I wanted to do was get all of the ARM devs mad at me too).
