Multiple function definitions in the same repo

[aashu2303]

Found 15 instances of function "func" in "ebpf-samples" repository. Developer should make a decision based on context but not on the function name.
Reasons:

1. Might be due to preprocessor directives for multiple OS.
2. Using generic name "func" for showing different ebpf functionality

We need to be cognizant of this, during extraction, lets highlight the same in the README. @aashu2303 can you take a stab?
