New Revision: 286670
URL: https://svnweb.freebsd.org/changeset/base/286670
Log:
Properly return ENOTDIR when calling *at() on a non-vnode.
We already properly return ENOTDIR when calling *at() on a non-directory
vnode, but it turns out that if you call it on a socket, we see EINVAL.
Patch up namei to properly translate this to ENOTDIR.
