[PATCH v2] selftests/bpf: Fix bind{4,6} tcp/socket header type conflict

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



There is a potential for us to hit a type conflict when including
netinet/tcp.h with sys/socket.h, we can remove these as they are not
actually needed.

Fixes errors like:
