            Bug ID: 209558
           Summary: Wakeup only one thread while kqueue events are
                    available
           Product: Base System
           Version: 11.0-CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: kern
          Assignee: freebsd-bugs@FreeBSD.org
          Reporter: andy.yx.chen@outlook.com

There is no reason to wakeup all threads while there are events available, as
that would make same event to be consumed by multiple threads at the same time
and result in errors.
