[RFC PATCH V2 0/5] vhost: accelerate metadata access through vmap()
...ll work equally
optimally on 32bit with <= 700M of RAM.
Talking to Jerome about the set_page_dirty issue, he raised the point
of what happens if two thread calls a mmu notifier invalidate
simultaneously. The first mmu notifier could call set_page_dirty and
then proceed in try_to_free_buffers or page_mkclean and then the
concurrent mmu notifier that arrives second, then must not call
set_page_dirty a second time.
With KVM sptes mappings and vhost mappings you would call
set_page_dirty (if you invoked gup with FOLL_WRITE) only when
effectively tearing down any secondary mapping (you've got pointers...

[PATCH 00/12] block/bio, fs: convert put_page() to put_user_page*()
From: John Hubbard <jhubbard at nvidia.com>
