From eed138d67d99312f07ed3bc326903b6808885571 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 19 Sep 2024 23:38:01 -0600 Subject: io_uring: improve request linking trace Right now any link trace is listed as being linked after the head request in the chain, but it's more useful to note explicitly which request a given new request is chained to. Change the link trace to dump the tail request so that chains are immediately apparent when looking at traces.
