From 94d57442e56d2ad2ca20d096040b8ae6f216a921 Mon Sep 17 00:00:00 2001 From: Anuj Gupta Date: Thu, 5 Dec 2024 11:51:09 +0530 Subject: io_uring: expose read/write attribute capability After commit 9a213d3b80c0, we can pass additional attributes along with read/write. However, userspace doesn't know that. Add a new feature flag IORING_FEAT_RW_ATTR, to notify the userspace that the kernel has this ability.
