VFS/fsstack: handle 32-bit smp + preempt + large files in fsstack_copy_inode_size
Copy the inode size and blocks from one inode to another correctly on 32-bit
systems with CONFIG_SMP, CONFIG_PREEMPT, or CONFIG_LBDAF. Use proper inode
spinlocks only when i_size/i_blocks cannot fit in one 32-bit word.
