Unless I'm misunderstanding this issue, no official glibc release was ever affected which makes the probability of other people being affected pretty small. And this issue is about backwards compatibility only insofar, that it works around a bug in some ancient cvs versions of glibc. Is it a new policy that the kernel mustn't break any buggy userspace code? > Linus cu Adrian -- "Is there not promise of rain?" Ling Tan asked suddenly out of the darkness.
