New Revision: 195909
URL: http://svn.freebsd.org/changeset/base/195909

Log:
  We don't support ephemeral IDs in FreeBSD and without this fix ZFS can
  panic when in zfs_fuid_create_cred() when userid is negative. It is
  converted to unsigned value which makes IS_EPHEMERAL() macro to
  incorrectly report that this is ephemeral ID. The most reasonable
  solution for now is to always report that the given ID is not ephemeral.
