The influx logic in knote_fdclose() is a little misguided, the resulting wakeup() call should always be redundant: knote_drop_detached() will always issue a wakeup before it returns, so anything waiting on *that* knote that had entered fluxwait should have been woken up then. This is the obvious divergence from the other influx/wakeup pattern in the implementation, which will kn_influx-- and then issue the wakeup after it has processed all of the knotes it can make progress on. While we're here, the kq_knlist cannot shrink, so we can avoid that condition in the loop and avoid potentially excessive wakeups from fluxwait on kqueues that we didn't touch.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
