We have observed hangs of the io_uring subsystem when using a
Linux kernel newer than 5.10. Also 5.15-rc6 is affected by this.

The exact cause of the hangs has not been diagnosed yet.
As a safety measure, we will disable innodb_use_native_aio by default
when the server has been configured with io_uring and the kernel
version is between 5.11 and 5.15.

If the start-up parameter innodb_use_native_aio=ON is set, then
we will issue a warning to the server error log.
