What do you mean by "sync?" If you mean an operation that brings an on
disk image of a filesystem into a consistent state then you cannot
delay any writeout until after it.
If you mean an ordinary update of the file (and directory) contents
then such capability must be coded at the filesystem level because
only the specific filesystem knows what are metadata and what are data
and what files different metadata belong to.
