This patchset tries to address the issue raised in
https://bugzilla.redhat.com/show_bug.cgi?id=2023977 .

Patch 2 and patch 3 are dependent on patch 1.
Patch 1 makes some code cleanup to make thing more readable and also is
a preparatory patch for patches 2 and 3. Patch 2 is the actual fix.
Patch 3 adds an additional assertion because of changes introduced in
patch 2.

comments in code to more accurately reflect the fix.
