This is unnecessary because this file includes wtf/Forward.h.

Done.

I recommend to add |using fileSystemIdPreparationCallback = void
(*)(DataObject&, const String&);|

[tasak, 2015/02/25 08:15:24]

Done.

m_prepareMethod -> s_prepareCallback

'method' usually means 'member function'.  This function is not limited to a
member.

[tasak, 2015/02/25 08:15:24]

Done.
