From 7e8c328c4e96a0fc68d9f1264656683f7f1e12c1 Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Wed, 29 May 2019 10:36:09 -0700 Subject: [PATCH] libbpf: simplify two pieces of logic Extra check for type is unnecessary in first case. Extra zeroing is unnecessary, as snprintf guarantees that it will zero-terminate string.
