From 1c0aa1fae1acb77c5f9917adb0e4cb4500b9f3a6 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Sat, 20 Feb 2021 11:55:28 -0700 Subject: io_uring: flag new native workers with IORING_FEAT_NATIVE_WORKERS A few reasons to do this: - The naming of the manager and worker have changed. That's a user visible change, so makes sense to flag it. - Opening certain files that use ->signal (like /proc/self or /dev/tty) now works, and the flag tells the application upfront that this is the case. - Related to the above, using signalfd will now work as well.
