ocfs2: Pass struct ocfs2_caching_info to the journal functions.
The next step in divorcing metadata I/O management from struct inode is to pass struct ocfs2_caching_info to the journal functions. Thus the journal locks a metadata cache with the cache io_lock function. It also can compare ci_last_trans and ci_created_trans directly. This is a large patch because of all the places we change ocfs2_journal_access..(handle, inode, ...) to ocfs2_journal_access..(handle, INODE_CACHE(inode), ...).
