ocfs2: Introduce dir free space list
The only operation which doesn't get faster with directory indexing is insert, which still has to walk the entire unindexed directory portion to find a free block. This patch provides an improvement in directory insert performance by maintaining a singly linked list of directory leaf blocks which have space for additional dirents.
