I think curthread is somewhat redundant since KTR always logs thread IDs.

... ah, I see it is in other KTR messages, so we should at least be consistent.

Yes. Although, it looks like there are only 4 others. We could fix those not to print thread instead? How thread is printed in uma_core.c is kind of weird anyway ("%x").

Separately it looks like ktr_tracepoint/ktr_verbose doesn't print the thread. I don't know if we care to change that.

I'd be fine with dropping the thread from the KTR messages. I think they used to be plain printf()s and were converted mechanically, which would explain why they're there.

Hmm, I don't think I've ever used ktr_verbose before. I agree that it should print the thread pointer as well.

markj feedback, don't print threads
