The STACK_GROWSUP case of stack expansion was missing a test for 'prev', which got removed by commit cb8f488c ("mmap.c: deinline a few functions") by mistake. I found my original email in "sent" folder. The patch in that mail does NOT remove !prev. That change had beed added by someone else. Ok, I think we are not much interested in who did it, let's fix it for good. [ "It looks like this was caused by me fixing rejects. That was the fancy include-lots-of-context-so-it-wont-apply patch." - akpm ] Reported-and-bisected-by: NHelge Deller <deller@gmx.de> Signed-off-by: NDenys Vlasenko <vda.linux@googlemail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Jiri Kosina <jkosina@suse.cz> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
