From 8165b566049b14152873011ea540eb22eae5111d Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 23 Jun 2023 10:33:11 -0600 Subject: io_uring/cancel: add IORING_ASYNC_CANCEL_USERDATA Add a flag to explicitly match on user_data in the request for cancelation purposes. This is the default behavior if none of the other match flags are set, but if we ALSO want to match on user_data, then this flag can be set.
