Hello, Some of these patches were send few years back, I saw that first version was send to this list in 2010, and after version 4 did not land [1]. Some days ago I resend the patches [2] and few hours later I noticed that one year ago was send a v5 version [3] and I was not aware. There was some discussion about v5 and during the discussion Mike Snitzer proposed that at least a change of the syntax is required, we're really interested on see this upstream as is extensively used in ChromeOS based devices so I'm wondering if we can restart the discussion and hopefully we will be able to do the modifications needed. So my first question is, apart of the change of the syntax, what more should be changed?
