If this method returns an `ENOSYS` error then the kernel will treat it as success and all
subsequent calls to `fsync` will be handled by the kernel without being forwarded to the
file system.
Synchronize file contents . File systems must ensure that the file contents have been flushed to disk before returning from this method . If ` datasync ` is true then only the file data ( but not the metadata ) needs to be flushed . If this method returns an ` ENOSYS ` error then the kernel will treat it as success and all subsequent calls to ` fsync ` will be handled by the kernel without being forwarded to the file system .
