A while back, Cc: Vincent Whitchurch <vincent.whitchurch@axis.com> proposed these patches: https://lore.kernel.org/lkml/20200825153338.17061-1-vincent.whitchurch@axis.com/
his approach adds a single flag, +x or (my pref) +T which sends the pr_debug to tracefs, independent of +p. Steve Rostedt offered feedback on one of the versions, and one could read that as provisional acceptance.
Ive worked his patchset since, it is here: https://github.com/jimc/linux/tree/dd-trc-11 (it has some unrelated bits too)
but it sits atop another patchset: https://lore.kernel.org/lkml/20230911230838.14461-1-jim.cromie@gmail.com/ or for git remote add https://github.com/jimc/linux/tree/dd-fix-5i
syslog and/or tracefs seems sufficient, do you have a 3rd destination ?
thanks
