The changes based on "kernel test robot" reports are properly folded
into this patch, but unless the tag - "Acked-by", "Reported-by" - is
qualified, it refers to the entire patch.  Let's limit it as:

Reported-by: kernel test robot <rong.a.chen@...el.com> # sleeping
function called from invalid context
Reported-by: kbuild test robot <lkp@...el.com> # sparse symbol
ima_queued_key() should be static
