Subject: [PATCH bpf-next] libbpf: fix compilation warning due to mismatched printf format
Date: Tue, 8 Feb 2022 22:39:09 -0800 [thread overview]
Message-ID: <20220209063909.1268319-1-andrii@kernel.org> (raw)
On ppc64le architecture __s64 is long int and requires %ld. Cast to
ssize_t and use %zd to avoid architecture-specific specifiers.
Fixes: 4172843ed4a3 ("libbpf: Fix signedness bug in btf_dump_array_data()")
Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
