  Log:
  SVN rev 207700 on 2010-05-06 15:52:08Z by alc
  
  Eliminate a small bit of unneeded code from kern_sendfile(): While
  kern_sendfile() is running, the file's vm object can't be destroyed
  because kern_sendfile() increments the vm object's reference count.  (Once
  kern_sendfile() decrements the reference count and returns, the vm object
  can, however, be destroyed.  So, sf_buf_mext() must handle the case where
  the vm object is destroyed.)
