can not change dir's owner

[zhangzewen]

I use s3fs-fuse mount a bucket， i create a folder in the mounted folder， when i use chown to change the folder's owner ， it can not be changed。But if it's a file, that worked.

Steps to Reproduce (for bugs)

# mkdir /opt/test_dir
# s3fs test /opt/test_dir -o use_path_request_style -o url=http://10.218.0.64:9000 -o endpoint=us-east-1 -o allow_other -o mp_umask=000
# cd /opt/test_dir/
# mkdir  test_dir
# touch  test
# ll
total 1
-rw-r--r-- 1 root root 0 Jan  7 18:20 test
drwxr-x--- 1 root root 0 Jan  7 18:16 test_dir
# chown operator test
# ll

@zhangzewen we don't support directories like AWS S3 and do not allow custom metadata on them.

It's a use case we are not interested to address anytime in near future. Closing this as won't fix.
