2020-09-18vlib: add decrement counter methodSergey Matov1-0/+19
Currently there is no way to decrease simple counter. To extend counters API new method allows to decrement counter by given value. This might be useful in implementation of statistics stored in stats segment.

2018-09-17STATS: Dynamically mapped shared memory segmentOle Troan1-11/+2

2017-04-06Use thread local storage for thread indexDamjan Marion1-8/+8
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
