State-Changed-When: Tue Jan 2 05:44:18 PST 1996
State-Changed-Why: 
Fixed in devfs_tree.c rev 1.12 and devfs_vfsops.c rev 1.9

The problem was due to the way that there is an internal, invisible
devfs mounted and used as a "blueprint" for newly mounted devfs trees.
The internal mounted tree was not completely initialised, and the
mount->mnt_op pointer was NULL.  The statfs() call on the nodes in
the mounted devfs was ending up back at at the internal filesystem with
a NULL operations vector.
