[PATCH bpf-next v2 0/2] selftests/bpf: Replaces CHECK macros and adds malloc failure checks to bpf_iter

[Yuran Pereira]

This patch series contains the following updates:
- Replaces the usage of all the CHECK macros in bpf_iter
  to the appropriate ASSERT_* macro calls
- Adds appropriate malloc failure checks to bpf_iter

Changes in v2:
- Removed unused "duration" variable which caused compilation error
  as reported by Yonghong Song [1]
- Improved malloc failure handling as suggested by Kui-Feng Lee [2]
- Ensured propper patch formatting (i.e. sending it as a set instead
  of two distinct patches)

For the cover letter, you can just put it at the same directory of
patch 1 and 2 and sent them with "git send-email" at once. All of them
will be in the same thread.

"git format-patch --cover-letter ..." will generate a template
of the cover letter along with patches. FYI

Hello Kui-Feng, thanks for the feedback.

So I did use "git format-patch --cover-letter", but for some reason
"git send-email /path-to-patches/" seems to be deliberately sending
the cover letter on a separate thread. IDK why.

But "git send-email --compose" seems to be working as expected, so
I'll use that and manually copy the cover letter generated by
format-patch to ensure it's all on the same thread.

Since I already butchered this thread, I will send v3 series on a 
separate thread. But I'll ensure to reference this thread on the 
cover letter.

I'll be more careful with future patches.
