A general note: have you considered turning it into a FreeBSD syscall, living in eg sys/kern/kern_eventfd.c, with a Linux wrapper around it? This - and some other Linux-specific syscalls - could end up making porting software easier.

sys/compat/linux/linux_event.c
523	Use UMA with its own zone instead of malloc with M_EPOLL? You could then move mtx_init/mtx_destroy into ctor/dtor.

ugh, I can, it seems to me that we need discuss it in public, some people ask me to make native epoll also.

After D2172 rewrite as a tiny wrapper.
