io_uring/eventfd: move eventfd handling to separate file This is pretty nicely abstracted already, but let's move it to a separate file rather than have it in the main io_uring file. With that, we can also move the io_ev_fd struct and enum out of global scope. Signed-off-by: Jens Axboe <axboe@kernel.dk> 2024-06-03 11:51:19 -06:00

io_uring/eventfd: dedup signalling helpers Consolidate io_eventfd_flush_signal() and io_eventfd_signal(). Not much of a difference for now, but it prepares it for following changes.
