From aef70a1f44c0b570e6345c02c2d240471859f0a4 Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Wed, 25 Sep 2019 11:30:38 -0700 Subject: libbpf: fix false uninitialized variable warning Some compilers emit warning for potential uninitialized next_id usage. The code is correct, but control flow is too complicated for some compilers to figure this out. Re-initialize next_id to satisfy compiler.
