Define 2 flags to be passed in the `flags' argument of the fsync vnode 

operator:

  * FSYNC_WAIT, which requests the synchronization operation to not return
    until completition,

  * FSYNC_DATAONLY, which is a hint: if possible, synchronize file data
    only.  If it's not feasible for a file system implementation to omit
    file status synchronization when synchronizing file data, this is ignored.
