I have a doubt,
What I seems to understand :
when a client makes a req to rgw, then the req is spawn into multiple
threads and the each of the thread will have its own req_state instances,
and so if I define any data structure inside req_state then there cant be
any race condition right to that data structure
Am I right? If not then does this mean that req_state is global to multiple
threads and there is chance of race condition?
