From 130a82760718997806a618490f5b7ab06932bd9c Mon Sep 17 00:00:00 2001 From: Caleb Sander Mateos Date: Mon, 5 Jan 2026 14:05:42 -0700 Subject: [PATCH] io_uring/register: drop io_register_enable_rings() submitter_task check io_register_enable_rings() checks that the io_ring_ctx is IORING_SETUP_R_DISABLED, which ensures submitter_task hasn't been assigned by io_uring_create() or a previous io_register_enable_rings() call. So drop the redundant check that submitter_task is NULL.
