From 4727dc20e0422211a0e0c72b1ace4ed6096df8a6 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Wed, 17 Feb 2021 08:48:00 -0700 Subject: arch: setup PF_IO_WORKER threads like PF_KTHREAD PF_IO_WORKER are kernel threads too, but they aren't PF_KTHREAD in the sense that we don't assign ->set_child_tid with our own structure. Just ensure that every arch sets up the PF_IO_WORKER threads like kthreads in the arch implementation of copy_thread().
