From ef05918d8135d4e5f2ca09739aeeb79ec60895a5 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Mon, 25 Mar 2024 18:53:33 -0600 Subject: [PATCH] io_uring: use the right type for work_llist empty check BugLink: https://bugs.launchpad.net/bugs/2071621 [ Upstream commit 22537c9f79417fed70b352d54d01d2586fee9521 ] io_task_work_pending() uses wq_list_empty() on ctx->work_llist, but it's not an io_wq_work_list, it's a struct llist_head. They both have ->first as head-of-list, and it turns out the checks are identical. But be proper and use the right helper.
