This is purely a cosmetic change to make it a little easier on the eyes, rather than jumping back to the else branch up top. Re-flow it to use another loop on the outside and just inline the re-lock before we repeat after awaking from fluxwait. The !killkn path should maybe issue a wakeup if there's a thread in KQ_SLEEP so that userland can observe the EOF, but this isn't a practical problem today: pretty much every case of knlist_clear is tied to a file descriptor and called in the close(2) path. As a consequence, potentially affected knotes are almost always destroyed before we even get to knlist_clear(). Reviewed by: kib, markj Differential Revision: https://reviews.freebsd.org/D56226

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.
