ocfs2: Change metadata caching locks to an operations structure.
We don't really want to cart around too many new fields on the ocfs2_caching_info structure. So let's wrap all our access of the parent object in a set of operations. One pointer on caching_info, and more flexibility to boot. Signed-off-by: Joel Becker <joel.becker@oracle.com>
