New Revision: 235397
URL: http://svn.freebsd.org/changeset/base/235397

Log:
  MFC: r234742
  It was reported via email that some non-FreeBSD NFS servers
  do not include file attributes in the reply to an NFS create RPC
  under certain circumstances.
  This resulted in a vnode of type VNON that was not usable.
  This patch adds an NFS getattr RPC to nfs_create() for this case,
  to fix the problem. It was tested by the person that reported
  the problem and confirmed to fix this case for their server.
