Issue

A windows client copying data to a share using the cifs protocol will follow the following steps repeated for each file he needs to copy
create the file
write to the file
close the file
open the file again checking for both attributes and extended attributes
Due to the nature of the current implementation of writeback, the last opening will trigger the cache to be flushed back to the origin and that opening will be delayed for as long as it takes for all the data to reach the origin.
