Is there any info lurking on what the vnode 'lock' actually covers?

I've a layered fs (that doesn't require any external support) I
keep thinking of porting to netbsd (from SVR4MP).  It basically
works by keeping reference counts on the lower vnodes - but SVR4
only locks vnodes during read and write.
