Error in StrategySyncStart() prologue

Hi,
The prologue of StrategySyncStart() mentions BufferSync(), but the
latter function does not call the first function. Instead
StrategySyncStart() is called by BgBufferSync() which uses the buffer
id provided by the first function to decide the buffer from where to
start syncing as mentioned in the first function's prologue.
BufferSync, on the other hand, scans all the buffers and does not use
the output of StrategySyncStart(). I think the prologue of
StrategySyncStart() intends to refer to BgBufferSync() and not
BufferSync(). PFA patch fixing the prologue.
