SVN rev 185956 on 2008-12-12 00:57:38Z by marcus
Add a new VOP, VOP_VPTOCNP, which translates a vnode to its component name
on a best-effort basis. Teach vn_fullpath to use this new VOP if a
regular VFS cache lookup fails. This VOP is designed to supplement the
VFS cache to provide a better chance that a vnode-to-name lookup will
succeed.
Currently, an implementation for devfs is being committed. The default
implementation is to return ENOENT.
A big thanks to kib for the mentorship on this, and to pho for running it
through his stress test suite.
