From 53c8036cb715f3577a7fe1db6e6ad06e8697b36f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 25 May 2018 23:33:19 +0200 Subject: bpf: btf: avoid -Wreturn-type warning gcc warns about a noreturn function possibly returning in some configurations: kernel/bpf/btf.c: In function 'env_type_is_resolve_sink': kernel/bpf/btf.c:729:1: error: control reaches end of non-void function [-Werror=return-type] Using BUG() instead of BUG_ON() avoids that warning and otherwise does the exact same thing.
