From d14b56f508ad70eca3e659545aab3c45200f258c Mon Sep 17 00:00:00 2001 From: Michal Hocko Date: Thu, 28 Jun 2018 17:53:06 +0200 Subject: [PATCH] net: cleanup gfp mask in alloc_skb_with_frags alloc_skb_with_frags uses __GFP_NORETRY for non-sleeping allocations which is just a noop and a little bit confusing. __GFP_NORETRY was added by ed98df3361f0 ("net: use __GFP_NORETRY for high order allocations") to prevent from the OOM killer. Yet this was not enough because fb05e7a89f50 ("net: don't wait for order-3 page allocation") didn't want an excessive reclaim for non-costly orders so it made it completely NOWAIT while it preserved __GFP_NORETRY in place which is now redundant. Drop the pointless __GFP_NORETRY because this function is used as copy&paste source for other places. Reviewed-by: Eric Dumazet Signed-off-by: Michal Hocko Signed-off-by: David S.
