It's supposed to be just like linux futex. > 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).
