  Modified:    sbin/mount  mount.c
  Log:
  Do not allow the caller to specify the same path for the special
  device file and the mount point.  This prevents the "unexpected recursive
  lock" panic from happening.
  
  This is a temporary fix.  A kernel fix would be much much more ugly than
  this, and still wouldn't be the "right" way to fix it.  After some
  of Terry's file system rework is installed, it will be possible to
  properly fix this problem in a clean manner.  Until then,
  this change should prevent use from getting a problem report
  on this every month or so (and I just noticed that someone in
  one of the freebsd news groups was complaining about this problem, too).
