Subject: [uml-devel] [PATCH 1/4] um: Fix _FORTIFY_SOURCE=2 support for kernel modules
Date: Tue, 28 Jun 2011 00:15:28 +0200 [thread overview]
Message-ID: <1309212931-19772-1-git-send-email-richard@nod.at> (raw)
When UML is compiled with _FORTIFY_SOURCE we have to
export all _chk() functions which are used in modules.
For now it's only the case for __sprintf_chk().
