Subject: [PATCH] samples/bpf: Fix cross compiler error with bpf sample
Date: Thu, 3 Aug 2017 22:46:23 -0700 [thread overview]
Message-ID: <20170804054623.5229-1-joelaf@google.com> (raw)
When cross-compiling the bpf sample map_perf_test for aarch64, I find that
__NR_getpgrp is undefined. This causes build errors. Fix it by allowing the
deprecated syscall in the sample.
