Any interest in reviewing / merging this and the other two patches sent together?
The DF_STATIC_TLS change is pretty short, the formatting patch is trivial.
As for the last patch introducing a comment change, I’m not sure what Mengqing’s stance is, but my intention for the comment change is to provide a better context for the reader rather than comparing to a solution that is not currently implemented in the codebase.

Tatsuyuki.
