We've been through this pick a better name thing several times :-/

Yes I agree, __GFP_MEMALLOC is a misnomer, however its consistent with
PF_MEMALLOC and __GFP_NOMEMALLOC - of which people know the semantics.

Creating a new name with similar semantics can only serve to confuse.

So unless enough people think its worth renaming all of them, I think
we're better off with this name.
