Question about fsync in copy-up operaton

[Chengguang Xu <cgxu519@xxxxxxxxxxxx>]

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
