Subject: [PATCH 3/6] selftest: include stdio.h in kselftest.h
Date: Fri, 18 Jan 2019 17:12:14 -0700	[thread overview]
Message-ID: <20190119001217.12660-4-tycho@tycho.ws> (raw)
In-Reply-To: <20190119001217.12660-1-tycho@tycho.ws>

While playing around with a way to skip the seccomp get_metadata test, I
noticed that this header uses printf() without defining it, leading to,

../kselftest.h: In function ‘ksft_print_header’:
../kselftest.h:61:3: warning: implicit declaration of function ‘printf’ [-Wimplicit-function-declaration]
   printf("TAP version 13\n");
   ^~~~~~
../kselftest.h:61:3: warning: incompatible implicit declaration of built-in function ‘printf’
../kselftest.h:61:3: note: include ‘<stdio.h>’ or provide a declaration of ‘printf’

if user code doesn't also use printf.
