It seems like a different issue.  A separate rule might be better.  Also,
there is no patch variant, so if one runs the patch mode on this script,
where the patch mode is useful, then one will miss the kvmalloc
suggestions completely.  Coccicheck has a mode where is first tries patch
and then report; I think 0-day uses this.
