From 62aa9805d123165102273eb277f776aaca908e0e Mon Sep 17 00:00:00 2001 From: Caleb Sander Mateos Date: Tue, 11 Feb 2025 17:51:18 -0700 Subject: [PATCH] io_uring: use lockless_cq flag in io_req_complete_post() io_uring_create() computes ctx->lockless_cq as: ctx->task_complete || (ctx->flags & IORING_SETUP_IOPOLL) So use it to simplify that expression in io_req_complete_post().
