commitebf57440ecupstream. Some of tests in xfstests failed with cifsd kernel server since commite80ddeb2f7. cifsd kernel server validates credit charge from client by calculating it base on max((InputCount + OutputCount) and (MaxInputResponse + MaxOutputResponse)) according to specification. MS-SMB2 specification describe credit charge calculation of smb2 ioctl : If Connection.SupportsMultiCredit is TRUE, the server MUST validate CreditCharge based on the maximum of (InputCount + OutputCount) and (MaxInputResponse + MaxOutputResponse), as specified in section 3.3.5.2.5. If the validation fails, it MUST fail the IOCTL request with STATUS_INVALID_PARAMETER. This patch add indatalen that can be a non-zero value to calculation of credit charge in SMB2_ioctl_init().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
