Subject: linux-next: build failure after merge of the bpf-next tree
Date: Thu, 18 Apr 2019 11:57:48 +1000 [thread overview]

Hi all,
After merging the bpf-next tree, today's linux-next build (powerpc perf)
failed like this:
In file included from xsk.c:32:
libbpf_util.h:49:3: error: #warning Architecture missing native barrier functions in libbpf_util.h. [-Werror=cpp]
# warning Architecture missing native barrier functions in libbpf_util.h.
^~~~~~~
cc1: all warnings being treated as errors
Caused by commit
b7e3a28019c9 ("libbpf: remove dependency on barrier.h in xsk.h")
I have applied the following patch for today ... please fix this.
