[0/3] Allow for multiple pages in a single writeback event

This is prep work for THP or Folios or whatever we end up doing --
we are going to end up somehow batching page writeback completions.
Nothing here makes that happen; we simply pass '1' from all our current
callers, but eventually we'll pass a number greater than 1.

Matthew Wilcox (Oracle) (3):
  mm/writeback: Rename __add_wb_stat to wb_stat_mod
  flex_proportions: Allow N events instead of 1
  mm/writeback: Change __wb_writeout_inc to __wb_writeout_add

The patches look good to me besides that one problem in the writeback
proportions code. After that is fixed, I can either take the patches
through my tree or we can route them through Andrew with my Reviewed-by.
