Yonghong Song 534e0e52bc samples/bpf: fix a compilation failure
samples/bpf build failed with the following errors:

  $ make samples/bpf/
  ...
  HOSTCC  samples/bpf/sockex3_user.o
  /data/users/yhs/work/net-next/samples/bpf/sockex3_user.c:16:8: error: redefinition of ‘struct bpf_flow_keys’
   struct bpf_flow_keys {
          ^
  In file included from /data/users/yhs/work/net-next/samples/bpf/sockex3_user.c:4:0:
  ./usr/include/linux/bpf.h:2338:9: note: originally defined here
    struct bpf_flow_keys *flow_keys;
           ^
  make[3]: *** [samples/bpf/sockex3_user.o] Error 1

Commit d58e468b11 ("flow_dissector: implements flow dissector BPF hook")
introduced struct bpf_flow_keys in include/uapi/linux/bpf.h and hence
caused the naming conflict with samples/bpf/sockex3_user.c.

The fix is to rename struct bpf_flow_keys in samples/bpf/sockex3_user.c
to flow_keys to avoid the conflict.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
