This is a cosmetic change, rather than a functional one: comparing the knlistsize against the fd requires a little bit of mental gymnastics to confirm that this is fine and not doing unnecessary work in some cases. Notably, one must consider that kq_knlistsize only grows in KQEXTENT chunks, which means that concurrent threads trying to grow the kqueue to consecutive fds will usually not result in the list being replaced twice. One can also more clearly rule out classes of arithmetic problems in the final `else` branch. Reviewed by: kib, markj Differential Revision: https://reviews.freebsd.org/D56209

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.
