Yes. The original regression was a null pointer deference issue. The
last 3 patches (actually) fix these issues introduced by the first 2
patches. Originally I only SRUed the first 3, and missed the other two
corrections. In addition I checked the latest upstream code and did not
find any other fixes to those sections of the code.

The original regression was the null pointer deference issues which were
found during validation of the original bug.

With these 5 patches, and a few weeks worth of testing I'm confident
this will address the original bug and not introduce additional regressions.
