Peng Tao 7c5465d6cc pnfsblock: alloc short extent before submit bio ... As discussed earlier, it is better for block client to allocate memory for tracking extents state before submitting bio. So the patch does it by allocating a short_extent for every INVALID extent touched by write pagelist and for every zeroing page we created, saving them in layout header. Then in end_io we can just use them to create commit list items and avoid memory allocation there.
