From: Andrii Nakryiko Date: Mon, 27 Jul 2020 22:47:15 +0000 (-0700) Subject: bpf: Fix bpf_ringbuf_output() signature to return long X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e1613b5714ee6c186c9628e9958edf65e9d9cddd;p=linux.git bpf: Fix bpf_ringbuf_output() signature to return long Due to bpf tree fix merge, bpf_ringbuf_output() signature ended up with int as a return type, while all other helpers got converted to returning long. So fix it in bpf-next now.
