Hi all,
It seems this causes a build fail on linux-next allmodconfig. I left
a mindless "git bisect run .." go against it and it came up with:
----------------------------
make[2]: *** [samples/seccomp/bpf-direct.o] Error 1
make[1]: *** [samples/seccomp] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [vmlinux] Error 2
5c5df77172430c6377ec3434ce62f2b14a6799fc is the first bad commit
