[LSF/MM] May I sneak in a new topic to MM track?

[Yang Shi <yang.shi@xxxxxxxxxxxxxxxxx>]

Hi folks,


I posted a patch series about mmap_sem scalability 
(https://lkml.org/lkml/2018/3/20/786), and got a lot great feedback. I'm 
working on v2 now (a little bit behind).  Could we sneak this in if 
anyone is interested? I saw Laurent has a topic about mmap_sem too, I'm 
supposed it is speculative page fault related.


Thanks,

Yang
