richard kennedy 9eb9104c66 btrfs: remove 64bit alignment padding to allow extent_buffer to fit into one fewer cacheline 
Reorder extent_buffer to remove 8 bytes of alignment padding on 64 bit
builds. This shrinks its size to 128 bytes allowing it to fit into one
fewer cache lines and allows more objects per slab in its kmem_cache.

slabinfo extent_buffer reports :-
