New series based on the discussion in the previous thread around
getting lock_page_memcg() out of rmap.

I beat on this with concurrent high-frequency moving of tasks that
partially share a swapped out shmem file. I didn't spot anything
problematic. That said, it is quite subtle, and Hugh, I'd feel better
if you could also subject it to your torture suite ;)

Thanks!

Against yesterday's mm-unstable.
