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.
