Subject: io_uring: use the right type for work_llist empty check
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=22537c9f79417fed70b352d54d01d2586fee9521;p=linux.git

io_uring: use the right type for work_llist empty check

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.
