[RFC,0/2] remove parameter 'compound' of add_file_rmap

Message

This is follow-up patch of "folio based filemap_map_pages()". Matthew
suggested to remove the parameter compound. Compare the folio page
number and parameter nr_pages to detect whether it's a 'compound'
operation.

Didn't remove 'compound' from page_remove_rmap() because it's not
ready yet.

Just did very limited test: boot to xfce GUI and used browser, email
client and Linux kernel build.

Yin Fengwei (2):
  rmap: Add function to handle entire folio rmap removing
  rmap: remove parameter 'compound' from foeio_add_file_rmap_range()
