wrstuden 9866514df5 Introduce layer library in genfs. This set of files abstracts most of ... the functionality of nullfs. The latter is now just a mount & unmount routine, and a few tables. umapfs borrow most of this infrastructure. Both fs's are now nfs-exportable. All layered fs's share a common format to private mount & private vnode structs (which a particular fs can extend). Also add genfs_noerr_rele(), a vnode op which will vrele/vput operand vnodes appropriately.		1999-07-08 01:18:59 +00:00
