hi, this patchset moves thread's map_groups to be dynamically allocated and shared within process threads.
The main benefit would be to be able to look up memory map from any thread that belongs to the process.
This implementes one of the solution ideas for issue described by Don in following thread: http://marc.info/?l=linux-kernel&m=139403876017159&w=2
This patches still has some loose ends, just wanted to hear opinions for this concept.
thanks, jirka
