Subject[PATCH] bpf: selftests: Fix warning in flow_dissector
Date
Building the userspace part of the flow_dissector resulted in:

prog_tests/flow_dissector.c: In function ‘tx_tap’:
prog_tests/flow_dissector.c:176:9: warning: implicit declaration
of function ‘writev’; did you mean ‘write’? [-Wimplicit-function-declaration]
return writev(fd, iov, ARRAY_SIZE(iov));
^~~~~~
write

Include <sys/uio.h> to fix this.
