GCC is simply wrong here - i have posted a workaround for that but it is too ugly to be merged upstream. > Handled-By : Andi Kleen > Patch : http://patchwork.kernel.org/patch/19330/ > http://patchwork.kernel.org/patch/19406/ This patch regresses on older GCC versions and doesnt really address the GCC false positive warning either, it just removes the inline function that triggers the warning.
