From 5b0764b2d34510bc87d33a580da98f77789ac36f Mon Sep 17 00:00:00 2001 From: Roman Gushchin Date: Tue, 1 Dec 2020 13:59:00 -0800 Subject: bpf: samples: Do not touch RLIMIT_MEMLOCK Since bpf is not using rlimit memlock for the memory accounting and control, do not change the limit in sample applications.
