As with the ongoing evolution of this, as previously discussed, the focus has settled on merging of anonymous VMAs and improving this mergeability. I have an RFC series (not upstreamed yet, but should be by LSF) which optionally permits improved anonymous mapping mergeability by passing a flag to mremap(). In this topic I'd like to discuss that, anon_vma in general motivations for it, why it's hard, etc. This dovetails with the original proposal - bit is a less ambitious, more short-term 'how can we improve the situation' kind of thing. Maybe next year there can be more :) My slides are at ~31 right now, so I wonder whether I could have an hour slot for this? As I'd also like to have some discussion of course! :) Thanks!
