From 99a10081647168022745859bb2f1c28b2f70dc83 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 19 Feb 2021 09:35:19 -0700 Subject: [PATCH] io_uring: make the !CONFIG_NET helpers a bit more robust With the prep and prep async split, we now have potentially 3 helpers that need to be defined for !CONFIG_NET. Add some helpers to do just that. Fixes the following compile error on !CONFIG_NET: fs/io_uring.c:6171:10: error: implicit declaration of function 'io_sendmsg_prep_async'; did you mean 'io_req_prep_async'? [-Werror=implicit-function-declaration] return io_sendmsg_prep_async(req); ^~~~~~~~~~~~~~~~~~~~~ io_req_prep_async Fixes: 93642ef88434 ("io_uring: split sqe-prep and async setup") Reported-by: Naresh Kamboju Signed-off-by: Jens Axboe --- fs/io_uring.c | 76 ++++++++++++++++++++--------------------------------------- 1 file changed, 26 insertions(+), 50 deletions(-) diff --git a/fs/io_uring.c b/fs/io_uring.c index 7956c67..cef8010 100644 --- a/fs/io_uring.c +++ b/fs/io_uring.c @@ -5128,56 +5128,32 @@ out: return 0; } #else /* !CONFIG_NET */ -static int io_sendmsg_prep(struct io_kiocb *req, const struct io_uring_sqe *sqe) -{ - return -EOPNOTSUPP; -} - -static int io_sendmsg(struct io_kiocb *req, unsigned int issue_flags) -{ - return -EOPNOTSUPP; -} - -static int io_send(struct io_kiocb *req, unsigned int issue_flags) -{ - return -EOPNOTSUPP; -} - -static int io_recvmsg_prep(struct io_kiocb *req, - const struct io_uring_sqe *sqe) -{ - return -EOPNOTSUPP; -} - -static int io_recvmsg(struct io_kiocb *req, unsigned int issue_flags) -{ - return -EOPNOTSUPP; -} - -static int io_recv(struct io_kiocb *req, unsigned int issue_flags) -{ - return -EOPNOTSUPP; -} - -static int io_accept_prep(struct io_kiocb *req, const struct io_uring_sqe *sqe) -{ - return -EOPNOTSUPP; -} - -static int io_accept(struct io_kiocb *req, unsigned int issue_flags) -{ - return -EOPNOTSUPP; -} - -static int io_connect_prep(struct io_kiocb *req, const struct io_uring_sqe *sqe) -{ - return -EOPNOTSUPP; -} - -static int io_connect(struct io_kiocb *req, unsigned int issue_flags) -{ - return -EOPNOTSUPP; -} +#define IO_NETOP_FN(op) \ +static int io_##op(struct io_kiocb *req, unsigned int issue_flags) \ +{ \ + return -EOPNOTSUPP; \ +} + +#define IO_NETOP_PREP(op) \ +IO_NETOP_FN(op) \ +static int io_##op##_prep(struct io_kiocb *req, const struct io_uring_sqe *sqe) \ +{ \ + return -EOPNOTSUPP; \ +} \ + +#define IO_NETOP_PREP_ASYNC(op) \ +IO_NETOP_PREP(op) \ +static int io_##op##_prep_async(struct io_kiocb *req) \ +{ \ + return -EOPNOTSUPP; \ +} + +IO_NETOP_PREP_ASYNC(sendmsg); +IO_NETOP_PREP_ASYNC(recvmsg); +IO_NETOP_PREP_ASYNC(connect); +IO_NETOP_PREP(accept); +IO_NETOP_FN(send); +IO_NETOP_FN(recv); #endif /* CONFIG_NET */ struct io_poll_table { -- 2.7.4
