I found an implementation from Tom Rini in 2005[1] and an out of tree implementation[2]. So I have a couple questions before I dive in: 1. Is anyone actively working on this? From lkml archives it appears no but I thought I'd ask. 2. Does anyone have an objection to this feature? From my reading it seems that the reason it was never merged was due to reliability issues but I just want to double check that people don't see some larger issue. I don't have 100% of my time to devote to this so it will likely take me a while but this is something I would like to see in the upstream kernel so I thought I'd give it a try.
