    sys/ufs/ufs          ufs_vnops.c 
  Log:
  Remove panics for rename() race conditions.  The panics are inappropriate
  because the IN_RENAME flag only fixes a few of the huge number of race
  conditions that can result in the source path becoming invalid even
  prior to the VOP_RENAME() call.  The panics created a serious security
  issue whereby an attacker could fairly easily cause the panic to
  occur, crashing the machine.
  
  The correct solution requires a great deal of work in the namei
  path cache code.
