By adding an extra argument to gfs2_trans_add_unrevoke we can now specify an extent length of blocks to unrevoke. This means that we only need to make one pass through the list for each extent rather than each block. Currently the only extent length which is used is 1, but that will change in the future. Also gfs2_trans_add_unrevoke is removed from gfs2_alloc_meta since its the only difference between this and gfs2_alloc_data which is left. This will allow a future patch to merge these two functions into one (i.e. one call to allocate both data and metadata in a single extent in the future).
