> Hi all, […]
for a struct osmo_time_cc *foo, you can use foo->total_sum. It holds the total 
sum in microseconds (1e-6).

osmo_time_cc doesn't use rbtree, will have to look closer to identify the 
problem

you're right, it's not the average indeed

another idea would be to have a separate accumulator for the release process 
(from established_onleave to unused_onenter). it should yield a fairly constant 
value in normal operation for all lchans. it would be easier to see chan 
release problems on a separate metric.
