From 7d8ca7250197096bfa9f432c1d99b0555504bbba Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sat, 18 Jun 2022 09:47:04 -0600 Subject: io_uring: add IORING_ASYNC_CANCEL_FD_FIXED cancel flag In preparation for not having a request to pass in that carries this state, add a separate cancelation flag that allows the caller to ask for a fixed file for cancelation.
