Subject: [NOMMU]: stub expand_stack() for nommu case
Date: Thu, 12 Jul 2007 22:07:50 +1000 [thread overview]
Message-ID: <200707121207.l6CC7ok9026564@goober> (raw)
Be consistent with VM mmap, implement expand_stack().
We can't actually do anything other than return an error
in the no MMU case though.
