This provides nicer message output. Since it seems more appropriate
for the nature of this module, also use KERN_INFO instead of other
levels.

You change the output here by more than just adding a prefix.
The first printk didn't have a newline.
The old code would print:
"rbtree testing -> <foo> cycles"
The new code prints:
"rbtree_test: rbtree testing"
"rbtree_test: -> <foo> cycles"
btw: each pr_info should have a newline termination
or be followed by a some number of pr_cont/printk with
the last one having a terminating newline.
The first pr_info here doesn't have a newline
so it's possible (though unlikely) that another
thread could have its output appended/interleaved
on the same line.

Ah, I see. This is actually the first time I'm using pr_* calls. I
actually don't mind the new format, it looked
ok, but if others don't agree, I can always resend it.

Your choice. I don't prefer one over the other.
I do prefer you add an explicit newline to the first
format though instead of relying on the implicit
newline the printk subsystem will emit during the next
pr_<level> call.

Why are you changing the ALERTs to INFO?

This is changing the output from KERN_ALERT to KERN_INFO. Why is this
necessary? Should this be pr_alert() instead?

Because of the nature of the messages. They don't justify having a
KERN_ALERT level (requiring immediate attention), and it seems a lot
more suitable to use INFO instead.

Hmm. I see interval_tree_test using the same alerts. It almost looks
like the start and end of a test are meant to be alerts. I am not
saying it shouldn't be changed, however looking for a stronger reason
than "it seems a lot more suitable to use INFO instead". Are there any
use-cases in which KERN_ALERTs cause problems?

No 'issue' particularly, just common sense. In any case I have no
problem reverting the changes back to KERN_ALERT, no big deal.
Andrew, Michel, do you have any preferences? I'm mostly interested in
patch 3/3, do you have any objections?

Sorry for the late reply - I have a lot of upstream email to catch up to.
No objection to the change but I also have to say I'm not quite sure
what's the motivation - it'd be easier if you had a 0/3 mail to
explain the issue. In particular, I'm not sure if you've been trying
to use the test compiled in rather than as a module (which is all I've
ever built it as myself :)
