:Agreed. The reason I didn't just add an example for MTX_SPIN mutexes is
:precisely not to encourage just blindly copying FreeBSD's fine-grained
:locking. Explaining alternative strategies and tradeoffs would require
:a seperate article of its own though.

Yah, I far prefer that people use lockmgr locks for most porting from
FreeBSD, if only to make debugging far, far easier. They aren't half
bad... over the years I've removed a lot of cruft from the lockmgr API,
it's actually pretty efficient.
The interrupt serializer is the best locking mechanism to use for drivers
which have interrupt service routines, but requires a bit more research
to use properly in a port vs lockmgr locks.
