I only need to store 'struct page *' there. sg_alloc_table() operates on 'struct statterlist' entries, which are 4 to 6 times larger than a simple 'struct page *' entry. I don't want to waste so much memory just for reusing a two function. Implementing the same idea with pure 'struct page *' pointers will be just a matter of a few lines.
