From b62e0efd8a8571460d05922862a451855ebdf3c6 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 13 Jun 2025 15:24:53 -0600 Subject: [PATCH] io_uring: run local task_work from ring exit IOPOLL reaping In preparation for needing to shift NVMe passthrough to always use task_work for polled IO completions, ensure that those are suitably run at exit time. See commit: 9ce6c9875f3e ("nvme: always punt polled uring_cmd end_io work to task_work") for details on why that is necessary.
