ocfs2: move ip_last_trans to struct ocfs2_caching_info
We have the read side of metadata caching isolated to struct ocfs2_caching_info, now we need the write side. This means the journal functions. The journal only does a couple of things with struct inode. This change moves the ip_last_trans field onto struct ocfs2_caching_info as ci_last_trans. This field tells the journal whether a pending journal flush is required. Signed-off-by: Joel Becker <joel.becker@oracle.com>
