[dpdk-dev] [PATCH v2] eal/interrupts: add function to allow interruptible epoll

[Thomas Monjalon]

> The existing definition of rte_epoll_wait retries if interrupted
> by a signal. This behavior makes it hard to use rte_epoll_wait
> for applications that want to use signals do do things like
> exit polling loop and shutdown.
> 
> Since changing existing semantic might break applications, add
> a new rte_epoll_wait_interruptible() function that does the
> same thing as rte_epoll_wait but will return -1 and errno of EINTR
> if it receives a signal.
