Hi Gang,

Hello Intel Kbuild team,

You just upgrade GCC version when compiling the latest kernel?

This report comes from a pretty old gcc:

       config: tile-allyesconfig (attached as .config)
       compiler: tilegx-linux-gcc (GCC) 4.6.2

Thanks,
Fengguang

Since these code looks a little old, I am sure that the related contributors 
are still work on OCFS2 project.


Thanks
Gang
