> Not to be super picky (OK I am super picky sometimes) can we change the name of the function rte_delay_us_sleep() to rte_sleep_us() the reason is delay and sleep conflict IMO. The rte_sleep_us() tells me it sleeps, which is a form of delay, but delay in DPDK assume busy wait.
I'm not sure about this, because this function intended to be used
as 'rte_delay_us_callback', i.e. as implementation of 'rte_delay_us()'.
IMO, it should state that it is the part of this API and that it
sleeps internally at the same time. So I tried to combine both "delay"
and "sleep" in one function name.
If we'll change the name to 'rte_sleep_us' it will look like alternative
to 'rte_delay_us', but it's one of its implementations.
'rte_delay_us_sleep' should be alternative to 'rte_delay_us_block()'.
I'd like to call it 'rte_delay_us_nonblock()', but it may be way more
confusing.
What do you think?
