    sys/ufs/ffs          ffs_vnops.c 
  Log:
  Merge from HEAD to RELENG_5_1:
  
    Return EOPNOTSUPP for attempted EA operations on VCHR vnodes in UFS2;
    if we permit them to occur, the kernel panics due to our performing
    EA operations using VOP_STRATEGY on the vnode.  This went unnoticed
    previously because there are very for users of device nodes on UFS2
    due to the introduction of devfs.  However, this can come up with
    the Linux compat directories and its hard-coded dev nodes (which will
    need to go away as we move away from hard-coded device numbers).
    This can come up if you use EA-intensive features such as ACLs and
    MAC.
  
    The proper fix is pretty complicated, but this band-aid would be
    an excellent MFC candidate for the release.
