Function definitions in headers are usually marked as 'static inline'. Since 'inline' is missing for crypto_reportstat(), if it were not referenced from a .c file that includes this header, it would produce a warning. Also, 'struct crypto_user_alg' is not declared in this header. I included <linux/crytouser.h> instead of adding the forward declaration as suggested [1]. Detected by compile-testing this header as a standalone unit: ./include/crypto/internal/cryptouser.h:6:44: warning: ‘struct crypto_user_alg’ declared inside parameter list will not be visible outside of this definition or declaration struct crypto_alg *crypto_alg_match(struct crypto_user_alg *p, int exact); ^~~~~~~~~~~~~~~ ./include/crypto/internal/cryptouser.h:11:12: warning: ‘crypto_reportstat’ defined but not used [-Wunused-function] static int crypto_reportstat(struct sk_buff *in_skb, struct nlmsghdr *in_nlh, struct nlattr **attrs) ^~~~~~~~~~~~~~~~~ [1] https://lkml.org/lkml/2019/6/13/1121 Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> --- Changes in v2: - include <linux/cryptouser.h> include/crypto/internal/cryptouser.h | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
