Modid:  2.4.x-xfs:slinx:138812a
linux/fs/xfs/xfs_log_recover.c - 1.254
        - during log recovery, delay allocating a chunk of memory until
          we know we are actually going to need it. Removes a leak in
          xlog_recover_add_to_trans().

linux/fs/xfs/xfs_dir_leaf.c - 1.108
        - always free allocated memory in xfs_dir_leaf_to_shortform
