SubjectRe: [ftrace-bpf 1/5] add BPF_PROG_TYPE_FTRACE to bpf
Hi,

Thank you for the patch! Yet something to improve:

[auto build test ERROR on linus/master]
[also build test ERROR on v4.14]
[cannot apply to next-20171114]
[if your patch is applied to the wrong git tree, please drop us a note to help improve the system]

url: https://github.com/0day-ci/linux/commits/yupeng0921-gmail-com/add-BPF_PROG_TYPE_FTRACE-to-bpf/20171114-202535
config: x86_64-randconfig-s3-11150026 (attached as .config)
compiler: gcc-6 (Debian 6.4.0-9) 6.4.0 20171026
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64

All errors (new ones prefixed by >>):

>> kernel/bpf/syscall.o:(.rodata+0x198): undefined reference to `ftrace_prog_ops'
