Re: Making forced unmounts work

["J. Hannken-Illjes" <hannken%eis.cs.tu-bs.de@localhost>]

Looks like this thread is dead.  No one beside David Holland is
interested and David objects.  I take back my proposal.


David wants to track information about threads running a vnode
operation from vnode_if.c. I have no idea how this could be done
without knowing file system implementation.

David wants forced unmounts to work even if a thread gets stuck
permanently in a vnode operation.  I don't see a way to safely
reclaim a vnode from a file system when this vnode is in use by
another thread.
