Hi, Guangqing.

The change log is preferred when you send a new version, which
can make people know the difference in this version quickly. It
could follow the SOB like this:

Signed-off-by: Chu Guangqing <chuguangqing@inspur.com>

v2:
- xxx
---

The content that wrapped by the "---" will not be visible after the
patch being applied, so you can put whatever you want here.

You titled the patch "samples/bpf: Fix spelling typo in samples/bpf",
but this file is not in the samples/bpf, right? So I think we'd better
split it out.

And it's preferred to tag you patch with "bpf" or "bpf-next", such
as [PATCH bpf-next V2], so the CI can run some testings for you,
even though it's not necessary for this patch.

BTW, "Guangqing Chu" will be better, according to the habit :)

Thanks!
