v2:
 - drop completion variables and flush workqueue [pmladek]
 - comment typo/pr_info cleanup [kbabulal/mbenes]
 - cleanup goto ret assignations [pmladek]
 - allocate pndup[]'s, leave some svar allocations to
   shadow_get_or_alloc() [pmladek]
 - change allocation order for cleaner test dmesg output [pmladek]

The test-klp-callbacks change implements a synchronization replacement of
initial code which relied on solely on sleep delays. Remove the sleeps
and pass a block_transition flag from test script to module. Use
flush_workqueue() to serialize module output for test result
consideration.

The test-klp-shadow-vars changes first refactors the code to be more of
a readable example as well as continuing to verify the component code.
The patch is broken in two to display the renaming and restructuring in
part 1 and the addition and change of logic in part 2. The last change
frees memory before bailing in case of errors.

Patchset to be merged via the livepatching tree is against: livepatching/for-next
