From 819a4f323579b56cd942f14718edd1f308adbbe2 Mon Sep 17 00:00:00 2001 From: Roman Gushchin Date: Tue, 1 Dec 2020 13:58:56 -0800 Subject: [PATCH] bpf: Eliminate rlimit-based memory accounting for xskmap maps Do not use rlimit-based memory accounting for xskmap maps. It has been replaced with the memcg-based memory accounting.
