From dc37dc617fabfb1c3a16d49f5d8cc20e9e3608ca Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Tue, 8 Feb 2022 22:39:09 -0800 Subject: [PATCH] libbpf: Fix compilation warning due to mismatched printf format On ppc64le architecture __s64 is long int and requires %ld. Cast to ssize_t and use %zd to avoid architecture-specific specifiers.
