sync() writes out all information in core memory that should be on disk. This includes modified super blocks, modified inodes, and delayed block I/O.
sync() should be used by programs that examine a file system, for example fsck.8 df.1v etc. sync() is mandatory before a boot.
The writing, although scheduled, is not necessarily complete upon return from sync().
