Yang Xiuwei a89c34babc io_uring: fix incorrect io_kiocb reference in io_link_skb ... [ Upstream commit 2c139a47eff8de24e3350dadb4c9d5e3426db826 ] In io_link_skb function, there is a bug where prev_notif is incorrectly assigned using 'nd' instead of 'prev_nd'. This causes the context validation check to compare the current notification with itself instead of comparing it with the previous notification. Fix by using the correct prev_nd parameter when obtaining prev_notif.
