Summary:
This simply writes the data passed in to the inode. Note that the current
implementation has a protocol violation since it doesn't sync the data written
to disk but advertise to the client that it did. This is completely wrong from
a data consistency guarantee, but is probably fine for now. Once the code
becomes closer to being production ready, this will be changed to honor the
client asks.
