Eric Dumazet 3cc4a84e02 proc: add a reschedule point in proc_readfd_common() ... User can pass an arbitrary large buffer to getdents(). It is typically a 32KB buffer used by libc scandir() implementation. When scanning /proc/{pid}/fd, we can hold cpu way too long, so add a cond_resched() to be kind with other tasks. We've seen latencies of more than 50ms on real workloads.
