Merge branch 'net-consolidate-page_is_pfmemalloc-usage'
Alexander Lobakin says:
====================
net: consolidate page_is_pfmemalloc() usage
page_is_pfmemalloc() is used mostly by networking drivers to test
if a page can be considered for reusing/recycling.
It doesn't write anything to the struct page itself, so its sole
argument can be constified, as well as the first argument of
skb_propagate_pfmemalloc().
In Page Pool core code, it can be simply inlined instead.
Most of the callers from NIC drivers were just doppelgangers of
the same condition tests. Derive them into a new common function
do deduplicate the code.
Resend of v3 [2]:
- it missed Patchwork and Netdev archives, probably due to server-side
issues.
Since v2 [1]:
- use more intuitive name for the new inline function since there's
nothing "reserved" in remote pages (Jakub Kicinski, John Hubbard);
- fold likely() inside the helper itself to make driver code a bit
fancier (Jakub Kicinski);
- split function introduction and using into two separate commits;
- collect some more tags (Jesse Brandeburg, David Rientjes).
Since v1 [0]:
- new: reduce code duplication by introducing a new common function
to test if a page can be reused/recycled (David Rientjes);
- collect autographs for Page Pool bits (Jesper Dangaard Brouer,
Ilias Apalodimas).
