i see
https://svnweb.FreeBSD.org/base/head/sys/sys/umtx.h?view=markup
but there seems to be no documentation for it in
https://www.freebsd.org/cgi/man.cgi
if _umtx_op does what it seems to do, then i think musl can be
ported to native freebsd syscalls, but i don't know how much
syscall abi stability freebsd is willing to guarantee.
i think historically that was assumed to be a private interface
between the libc and the kernel on bsd (in which case a musl port
cannot be easily maintained outside of the bsd source repo).
