Hmm, there are a number of changes in -mm that conflict with the 
description given in this document (element poisoning, DEFINE_FLEX_ARRAY, 
array shrinking, etc).  Perhaps this could be based on the -mm behavior 
and get pushed through Andrew so that it's consistent when merged for 
2.6.32?

Thanks for writing this up, it's very descriptive and understandable.  I 
think there's some question right now about whether flex arrays will be 
very popular given we haven't identified any potential users at the 
moment, though.  Adding this documentation may help in getting new code to 
use it and inspire existing code to convert, so I think it's a good idea 
if flex arrays are indeed here to stay.
