Hi Bart,

Thanks for the note, but checkpatch output on the entire tree (not just
the patchs I posted) does not really help the discussion.  Obviously
this is on my list before submission for Target_Core_Mod/ConfigFS for
v2.6.29.  However, what would be nice if you actually sent a kernel
patch for these issues.
