[PATCH] net, skbuff: Get rid of unused skb_propagate_pfmemalloc

From: mhocko
Date: Thu Aug 27 2015 - 04:46:51 EST


From: Michal Hocko <mhocko@xxxxxxxx>

It seems that skb_propagate_pfmemalloc has never had a user since it was
introduced by 0614002bb5f7 ("netvm: propagate page->pfmemalloc from
skb_alloc_page to skb"). Remove it.

Hi,
this has been noticed while working on 2f064f3485cd ("mm: make page
pfmemalloc check more robust").
