From 95ec66968571bf0af0a22effdc1b9d9e62ea6630 Mon Sep 17 00:00:00 2001 From: Joel Fernandes Date: Wed, 20 Sep 2017 09:11:56 -0700 Subject: samples/bpf: Use getppid instead of getpgrp for array map stress When cross-compiling the bpf sample map_perf_test for aarch64, I find that __NR_getpgrp is undefined. This causes build errors. This syscall is deprecated and requires defining __ARCH_WANT_SYSCALL_DEPRECATED. To avoid having to define that, just use a different syscall (getppid) for the array map stress test.
