From upstream tracker issue:
"""
Objects deep in directory tree are not visible without first performing 'ls' on all of its subpaths. As an example I have put one object into rgw bucket:

s3cmd -c .s3cfg2 put test.txt s3://ganesha/a/b/c/d/f/g/h/i/j/k/l/test
s3cmd -c .s3cfg2 ls s3://ganesha/ --recursive
2018-06-14 15:40 5 s3://ganesha/a/b/c/d/f/g/h/i/j/k/l/test

The problem is that after mounting it with nfs the file is not immediately visible - I have to traverse all of the directories one by one.
