All these questions can be resolved in the discussions of the individual 
interfaces if and when anyone works on patches to add wrappers for them.  
I'm simply trying to get an answer for "when should such wrappers be added 
at all?" other than "only for interfaces already in Linux 3.2 / glibc 
2.15", along with "what does a complete patch adding such a wrapper look 
like?", so there is a common basis for reviewing all such patches.
