Current support for iterating over mnt_vnodelist (the list of vnodes
attached to a specific mount point) is rudimentary. All we have is
vmark() / vunmark() to set a marker on the list. Every caller has
to care about list and vnode mutexes, reference count being zero,
intermediate vnode states lik

Add an interface to iterate over a vnode list:
void vfs_vnode_iterator_init(struct mount *mp, void **marker)
void vfs_vnode_iterator_destroy(void *marker)
bool vfs_vnode_iterator_next(void *marker, struc

Please explain in more detail why you prefer a typed pointer o

New diff at http://www.netbsd.org/~hannken/vnode-pass4-3.diff
Looks good to me now, assuming all tests pass with it. (Do we have
any automatic tests for ffs_reload &c.?)
The lfs changes look suspect -- there is nothing int
the tree.
With apologies to the mailing list archive (half a dozen files and
>2000 lines of code), I put it here:
