Subject: [PATCH] aio-posix: fix build failure io_uring 2.2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The io_uring fixed "Don't truncate addr fields to 32-bit on 32-bit":
https://git.kernel.dk/cgit/liburing/commit/?id=d84c29b19ed0b130000619cff40141bb1fc3615b
This leads to build failure:
../util/fdmon-io_uring.c: In function add_poll_remove_sqe:
../util/fdmon-io_uring.c:182:36: error: passing argument 2 of io_uring_prep_poll_remove makes integer from pointer without a cast [-Werror=int-conversion]
182 | io_uring_prep_poll_remove(sqe, node);
| ^~~~

| AioHandler *

cc1: all warnings being treated as errors
Use LIBURING_HAVE_DATA64 to check whether the io_uring supports 64-bit
variants of the get/set userdata, to convert the paramter to the right
data type.
