David,

Patch parts 1, 2 and 3 are essentially individual stand-alone patches, and can be merged as such.

I only made them part of this series because they were required for the primary patch 4.

When I have some time to spare, I will send a new patch, adding the nonnull and access attributes, based on the received feedback.


PS: This patch series got the wrong name by mistake.
