Can you log current->name & pid?
I am also thinking is a level down from warn would be better. Notice
sounds intuitively correct to me.
git grep -e 'pr.*obsolete' | grep warn | wc -l
21
git grep -e 'pr.*obsolete' | grep notice | wc -l
1
git grep -e 'pr.*obsolete' | grep info | wc -l
4
Looks like warn's back on the menu, boys.
Majority is just wrong. :P
I am also tempted by the _once alternative, but then it makes less sense
to include name & pid.
I'm more afraid that there are users out there that frequently poke
these files.
Agreed, I think best option is to go with ratelimited and name & pid
logged. And more verbosity about what has been access and what should be
accessed instead.
