This is a last part to remove the memory sharing for rb_tree in extent_cache.
This should also fix arm32 memory alignment issue.
[struct extent_node] [struct rb_entry]
[0] struct rb_node rb_node; [0] struct rb_node rb_node;
union { union {
struct { struct {
[16] unsigned int fofs; [12] unsigned int ofs;
unsigned int len; unsigned int len;
};
unsigned long long key;
} __packed;
