Subject: [PATCH net-next 0/3] net: constify page_is_pfmemalloc() and its users

page_is_pfmemalloc() is used mostly by networking drivers. It doesn't
write anything to the struct page itself, so constify its argument and
a bunch of callers and wrappers around this function in drivers.
In Page Pool core code, it can be simply inlined instead.

Alexander Lobakin (3):
  mm: constify page_is_pfmemalloc() argument
  net: constify page_is_pfmemalloc() argument at call sites
  net: page_pool: simplify page recycling condition tests
