[GIT PULL] io_uring support for get/setsockopt

[Jens Axboe]

Hi Linus,

On top of the core io_uring changes, this pull request adds support for
using getsockopt and setsockopt via io_uring. The main use cases for
this is to enable use of direct descriptors, rather than first
instantiating a normal file descriptor, doing the option tweaking
needed, then turning it into a direct descriptor. With this support, we
can avoid needing a regular file descriptor completely.

The net and bpf bits have been signed off on their side.

Please pull!
