it looks like you described the semaphores that are used in userspace.
The Semaphores section of the locking(9) man page should describe
in-kernel semaphores (kern_sema.c). They are implemented by a mutex and
a conditional variable.
Even though it's nice to have some utility functions in our kernel, I
always wondered why we have them. There isn't a lot of code in the tree
that uses them...
