From 57c8f63e8e7a4a95d7fcc49e3953341fb4039899 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Sun, 15 Jul 2007 23:38:28 -0700 Subject: [PATCH] nommu: stub expand_stack() for nommu case 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.
