    sys/ufs/ufs          ufs_extattr.c 
  Log:
  When performing a VOP_LOOKUP() as part of UFS1 extended attribute
  auto-start, set cnp.cn_lkflags to LK_EXCLUSIVE.  This flag must now
  be set so that lockmgr knows what kind of lock to acquire, and it
  will panic if not specified.  This resulted in a panic when using
  extended attributes on UFS1 as of locking work present in the 6.x
  branch.
  
  This is a RELENG_6_0 merge candidate.
