Pull ksmbd fixes from Steve French:
"Ten fixes for the ksmbd kernel server, for improved security and
additional buffer overflow checks:
- a security improvement to session establishment to reduce the
possibility of dictionary attacks
- fix to ensure that maximum i/o size negotiated in the protocol is
not less than 64K and not more than 8MB to better match expected
behavior
- fix for crediting (flow control) important to properly verify that
sufficient credits are available for the requested operation
- seven additional buffer overflow, buffer validation checks"

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.
