io_uring: clean up a type in io_uring_register_get_file()

2024-09-16T18:04:10+00:00

Originally "fd" was unsigned int but it was changed to int when we pulled this code into a separate function in commit 0b6d253e084a ("io_uring/register: provide helper to get io_ring_ctx from 'fd'"). This doesn't really cause a runtime problem because the call to array_index_nospec() will clamp negative fds to 0 and nothing else uses the negative values.

io_uring/register: provide helper to get io_ring_ctx from 'fd'

2024-09-12T16:14:05+00:00

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.

io_uring/register: move io_uring_register(2) related code to register.c

2023-12-19T15:54:20+00:00

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
