Reorganize data elements to reduce struct sizes
Thanks for the comments. I have incorportated them all. CONFIG_OCFS2_FS_STATS is enabled and CONFIG_DEBUG_LOCK_ALLOC is disabled. Statistics now look like - ocfs2_write_ctxt: 2144 - 2136 = 8 ocfs2_inode_info: 1960 - 1848 = 112 ocfs2_journal: 168 - 160 = 8 ocfs2_lock_res: 336 - 304 = 32 ocfs2_refcount_tree: 512 - 472 = 40 Signed-off-by: Goldwyn Rodrigues <rgoldwyn@suse.de> Signed-off-by: Joel Becker <joel.becker@oracle.com>
