Could use some basic coding style fixes too.

- Move assignments outside of if statement expression "if (err = foo_bar())"
- No C99-style comments "//"
- Use struct kmem_cache instead of the deprecated kmem_cache_t
- Don't use function-like macros as the left hand side of assignment
expression "itohi_ptr(inode) = kzalloc(size, GFP_KERNEL);". It's much
better to open-code the assignment or introduce a setter function
(e.g. inode_set_hiptr).
- Kill wrappers (e.g. unionfs_kill_block_super can be replaced with
generic_shutdown_super)
