Description

Some filesystems like NFS give functionality to client - "partial file data sync". But for all client's "partial
syncs" filesystem does "full file data sync" because there is no such functionality in VFS.

This can hit performance in case of client or application care only about part of file data at the moment.

Behavior should be like vfs_fsync_range() in linux.

No data to display
