From 2fe256a429cb6c0b0064563af4158470143a363c Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Wed, 24 Nov 2021 11:32:33 -0800 Subject: selftests/bpf: Migrate selftests to bpf_map_create() Conversion is straightforward for most cases. In few cases tests are using mutable map_flags and attribute structs, but bpf_map_create_opts can be used in the similar fashion, so there were no problems. Just lots of repetitive conversions.
