Re: [PATCH bpf-next 3/4] selftests/bpf: Add a null pointer check for the load_btf_spec

…

Add the malloc failure checking to avoid possible null dereference.

How do you think about the following wording variant?

Add a return value check so that a null pointer dereference will be avoided after a memory allocation failure.

Would you like to add the tag “Fixes” accordingly?

How do you think about to reuse the variable “errno” in such an error case?
