In looking at the mess of ion changes that are currently in the AOSP kernel tree (where android devices are pulled from), it looks almost nothing like what we currently have here in the mainline kernel tree. So if what we have here, today, is not of use to anyone who actually wants to use this interface, why are we keeping it around? John, why can't we just drop all of this code from the kernel today, and then Android will keep their own copy for their next LTS release anyway. It doesn't look like what we have here, and the merge issues it causes is a pain (as I know from having to do them...) So keeping this around in-tree any longer feels pointless to me, and actively causes me, and others, more work for no gain. I'll go make a patch set to just drop this code now... thanks, greg k-h _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
