  SVN rev 188231 on 2009-02-06 12:39:42Z by rwatson
  
  Merge r187790 from head to stable/7:
  
    Following a fair amount of real world experience with ACLs and
    extended attributes since FreeBSD 5, make the following semantic
    changes:
  
    - Don't update the inode modification time (mtime) when extended
      attributes (and hence also ACLs) are added, modified, or removed.
    - Don't update the inode access tie (atime) when extended attributes
      (and hence also ACLs) are queried.
  
    This means that rsync (and related tools) won't improperly think
    that the data in the file has changed when only the ACL has changed.
  
    Note that ffs_reallocblks() has not been changed to not update on an
    IO_EXT transaction, but currently EAs don't use the cluster write
    routines so this shouldn't be a problem.  If EAs grow support for
    clustering, then VOP_REALLOCBLKS() will need to grow a flag argument
    to carry down IO_EXT to UFS.
