New Revision: 226687
URL: http://svn.freebsd.org/changeset/base/226687
Log:
The only possible error return from null_nodeget() is due to insmntque1
failure (the getnewvnode cannot return an error). In this case, the
null_insmntque_dtr() already unlocked the reclaimed vnode, so VOP_UNLOCK()
in the nullfs_mount() after null_nodeget() failure is wrong.
