From 55de170382a92d6da6fc9f23efc21eb2f3d25126 Mon Sep 17 00:00:00 2001 From: Jesper Dangaard Brouer Date: Tue, 2 May 2017 14:31:50 +0200 Subject: samples/bpf: adjust rlimit RLIMIT_MEMLOCK for traceex2, tracex3 and tracex4 Needed to adjust max locked memory RLIMIT_MEMLOCK for testing these bpf samples as these are using more and larger maps than can fit in distro default 64Kbytes limit.
