What's more, seeing the changes in orangefs tree I would rather have
static void orangefs_free_inode(struct inode *inode)
{
	struct orangefs_inode_s *orangefs_inode = ORANGEFS_I(inode);
	kmem_cache_free(orangefs_inode_cache, orangefs_inode);
}

in that series; not only less noise on merge, but with additional
uses of orangefs_inode in the body from orangefs tree changes
keeping the local variable clearly makes sense...
