Subject: skbuff: constify skb_propagate_pfmemalloc() "page" argument
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=48f971c9c80a728646fc03367a28df747f20d0f4;p=linux.git

skbuff: constify skb_propagate_pfmemalloc() "page" argument

The function doesn't write anything to the page struct itself,
so this argument can be const.

Misc: align second argument to the brace while at it.
