mysqld: io_uring_queue_init() failed with errno 1

      The new parameter innodb_linux_aio controls which Linux implementation to use for innodb_use_native_aio=ON.

      innodb_linux_aio=auto is equivalent to innodb_linux_aio=io_uring when it is available, and falling back to innodb_linux_aio=aio when not.

      Previously, only one implementation (libaio or io_uring) was available. Currently, if io_uring is disabled in the environment, we will fall back to the older libaio interface.

    Description

      When starting the Docker container, docker logs tells me:
      2025-03-03 5:11:46 0 [Warning] mysqld: io_uring_queue_init() failed with errno 1
      2025-03-03 5:11:46 0 [Warning] InnoDB: liburing disabled: falling back to innodb_use_native_aio=OFF

      I worked before with 10..5.23. This one does not have those warns. The variable innodb_use_native_aio is still ON.
      I tested 10.11.6 and today the latest 10.11.11. They both have these warns.

      I am not sure how performance is affected by disabling native aio.
