Subject: [PATCH bpf-next] libbpf: fix pr_warn type warnings on 32bit
Date:   Fri,  4 Jun 2021 13:24:48 +0200
Message-Id: <20210604112448.32297-1-msuchanek@suse.de>
In-Reply-To: <CAEf4BzbgJPgVmdS32nnzd8mBj3L=mib7D8JyP09Gq4bGdYpTyg@mail.gmail.com>
References: <CAEf4BzbgJPgVmdS32nnzd8mBj3L=mib7D8JyP09Gq4bGdYpTyg@mail.gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The printed value is ptrdiff_t and is formatted wiht %ld. This works on
64bit but produces a warning on 32bit. Fix the format specifier to %td.

Fixes: 67234743736a ("libbpf: Generate loader program out of BPF ELF file.")
