Subject: [PATCH bpf-next] libbpf: Add cscope and TAGS targets to Makefile
Date: Thu,  3 Oct 2019 10:43:21 +0200	[thread overview]
Message-ID: <20191003084321.1431906-1-toke@redhat.com> (raw)

Using cscope and/or TAGS files for navigating the source code is useful.
Add simple targets to the Makefile to generate the index files for both
