I know that kqueues can be used in userland (with EVFILT PROC), can they be used as well from a KEXT? I don't have a good answer for your overall question (alas), but I can confirm that kqueues are not usable in the kernel (for this or anything else). This email sent to site_archiver@lists.apple.com
