Subject: selftests/bpf: Add -fms-extensions to bpf build flags
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=835a50753579aa8368a08fca307e638723207768;p=thirdparty%2Flinux.git

selftests/bpf: Add -fms-extensions to bpf build flags

The kernel is now built with -fms-extensions, therefore
generated vmlinux.h contains types like:
struct slab {
   ..
   struct freelist_counters;
};

Use -fms-extensions and -Wno-microsoft-anon-tag flags
to build bpf programs that #include "vmlinux.h"
