Jens Axboe fa780334a8 io_uring: silence variable ‘prev’ set but not used warning ... If io_uring.o is built with W=1, it triggers a warning: io_uring/io_uring.c: In function ‘__io_submit_flush_completions’: io_uring/io_uring.c:1502:40: warning: variable ‘prev’ set but not used [-Wunused-but-set-variable] 1502 | struct io_wq_work_node *node, *prev; | ^~~~ which is due to the wq_list_for_each() iterator always keeping a 'prev' variable. Most users need this to remove an entry from a list, for example, but __io_submit_flush_completions() never does that. Add a basic helper that doesn't track prev instead, and use that in that function.
