| |
From: Michal Hocko <mhocko@suse.com>
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.
Signed-off-by: Michal Hocko <mhocko@suse.com> --- Hi, this has been noticed while working on 2f064f3485cd ("mm: make page pfmemalloc check more robust").
