I think you meant here "add a pointer in `struct commit_graph` as well
as in `struct write_commit_graph_context`...".

Perhaps we should add the information that it is done that way to be
able to allocate topo_level_slab only when needed, in the
write_commit_graph(), and adding new member to those struct is required
to pass it through the call chain (modifying `struct commit_graph` is
needed for fill_commit_graph_info()).  But that might be too much detail
to put in the commit message.

All right, here we add new member to `struct commit_graph` type.

All right, here we add new member to `struct write_commit_graph_context`
type, which is local to commit-graph.c.

All right, here we define new slab for storing topological levels; this
just defines new type. Note that we do not define any setters and
getters to handle non-zero initialization, like we have for
commit_graph_data_slab.

I guess using get_be32() is repeated in this newly added part of code
because previous part would be changed to read in generation number v2,
if available, and we won't be then able to use

		*topo_level_slab_at(g->topo_levels, item) = graph_data->generation;

All right, that's smart.


I guess that in fill_commit_graph_info() we don't know if we are reading
commit-graph, when topo levels slab is not present, or whether we are
extending and writing the commit-graph file, when we need to fill it
with current commit-graph data.

The fact that fill_commit_graph_info() takes 'struct commit_graph' also
explains why we need to add pointer to a topo_levels slab to both
structs.

All right, we need topo_level_slab only for writing the commit-graph, so
we allocate it with init_*_slab() in write_commit_graph(), and set
pointers to it in `struct write_commit_graph_context *ctx` and in
`struct commit_graph` for each layer in the commit graph.  This is
needed to pass it down the call-chain.

Looks good to me.

All right, write_graph_chunk_data() is called from write_commit_graph(),
so we know that cxt->topo_levels is not NULL.

All right, we know that compute_generation_numbers() is called by the
write_commit_graph(), so we know that cxt->topo_levels is not NULL.

Also, we rename 'generation' to 'level' in preparation for the time when
we would be computing *both* topological level (for backward
compatibility) and corrected committer date (to be used as generation
number v2).  All right.

Same here, the results of renaming of 'generation' local variable to
'level'.

Similarly, we rename 'max_generation' to 'max_level'.

Continuation of those renames.

This is a bit safer way to handle possible overflow: instead of

  final = max_found + 1;            /* set to maximum plus 1 */
  if (final > MAX_POSSIBLE_VALUE)   /* handle overflow */
      final = MAX_POSSIBLE_VALUE;

where we can have problems if MAX_POSSIBLE_VALUE overflows, we use the
following pattern:

  if (max_found > MAX_POSSIBLE_VALUE - 1)  /* handle overflow */
      max_found > MAX_POSSIBLE_VALUE - 1;
  final = max_found + 1;                   /* set to maximum plus 1 */

It is just a bit obscured by renaming variable and switch to using
commit slab.

It is not that important for topological level, where
GENERATION_NUMBER_V1_MAX is smaller than maximum possible value, but it
would be important for generation number v2.
