-------------------------------------------
# ..provide a joint patch with both changes in
# presumably this patch is only going to benefit object stores where the cost
of any ls operation is high due to the need to set up an HTTP link for each

results?
> Improve getSplits() performance for fs implementations that can utilize
> performance gains from recursive listing
