[PATCH] cifs: advertise the right receive buffer size to the server

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, we mirror the same size back to the server that it sends us.
That makes little sense. Instead we should be sending the server the
maximum buffer size that we can handle.
