Module: sip-router Branch: master Commit: 291166681c62ca42c05d3b501482311aa51f8d0e URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=2911666… Author: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Committer: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Date: Mon Jun 14 19:11:59 2010 +0200 core: futexlock compilation workaround for OpenSuse 10.2 In some older linux distributions /usr/include/futex.h uses a __user attribute, which is defined in linux/compiler.h. However linux/compiler.h is not part of the kernel headers package in most recent distributions. Instead they ship a modified linux/futex.h that does not include <linux/compile.h> and does not use __user. "__user" is used only for checking pointer address space in the kernel (using the sparse tool and make C=1 or make C=2) so it's safe to define it as null/empty.
