io_uring/register: move io_uring_register(2) related code to register.c Most of this code is basically self contained, move it out of the core io_uring file to bring a bit more separation to the registration related bits. This moves another ~10% of the code into register.c. Signed-off-by: Jens Axboe <axboe@kernel.dk> 2023-12-19 15:54:20 +00:00			`// SPDX-License-Identifier: GPL-2.0`

io_uring/register: provide helper to get io_ring_ctx from 'fd' Can be done in one of two ways: 1) Regular file descriptor, just fget() 2) Registered ring, index our own table for that In preparation for adding another register use of needing to get a ctx from a file descriptor, abstract out this helper and use it in the main register syscall as well.
