kernel: add KERNEL_IO_URING option
* add KERNEL_IO_URING option NOTES: Adds configurable support for the io_uring interface (CONFIG_IO_URING) via KERNEL_IO_URING option. The kernel only zImage grows by about 5-9KB ? I would like to enable this by default for all 5.4 kernels, so i can use the new io_uring samba-4.12.x vfs module by default. The associated liburing was already submitted and merged. The kernel + liburing was tested on ARM/mvebu via samba4 vfs_io_uring module and i have no issues so far. Some extra reads on it and why we should enable it by default, since i expect more packages to use this in the future. https://wiki.samba.org/index.php/Samba_4.12_Features_added/changed#.27io_uring.27_vfs_module https://lwn.net/Articles/810414/ https://kernel.dk/io_uring.pdf https://www.phoronix.com/scan.php?page=news_item&px=Linux-5.6-IO-uring-Tests Signed-off-by: Andy Walsh <andy.walsh44+github@gmail.com>
