Subject: [PATCH] nommu: stub expand_stack() for nommu case
Date: Fri, 1 Jun 2007 21:09:21 +1000 [thread overview]
Message-ID: <200706011109.l51B9LbK023545@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.
