Hi Folks,

During copy-up when parent dir does not exist then will create parent 
dir first.
However, I noticed only regular file calls fsync in the end of copy-up 
operation,
so how newly created parent dir get synced in this case?


Thanks,
Chengguang

Looks like an oversight.  It should fsync parent dir as well.

Thanks,
