  Log:
  SVN rev 220937 on 2011-04-22 07:26:09Z by jh
  
  Utilize vfs_sanitizeopts() in vfs_mergeopts() to merge options. Because
  vfs_sanitizeopts() can handle "ro" and "rw" options properly, there is
  no more need to add "noro" in vfs_donmount() to cancel "ro".
  
  This also fixes a problem of canceling options beginning with "no".
  For example, "noatime" didn't cancel "nonoatime". Thus it was possible
  that both "noatime" and "nonoatime" were active at the same time.
