A mirror of the official Linux kernel repository just in case

If sd_max is unsigned, then sd_max - GSS_SEQ_WIN is a very large number
whenever sd_max is less than GSS_SEQ_WIN, and the comparison:
seq_num <= sd->sd_max - GSS_SEQ_WIN
in gss_check_seq_num is pretty much always true, even when that's
clearly not what was intended.
This was causing pynfs to hang when using krb5, because pynfs uses zero
as the initial gss sequence number. That's perfectly legal, but this
logic error causes knfsd to drop the rpc in that case. Out-of-order
sequence IDs in the first GSS_SEQ_WIN (128) calls will also cause this.

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.
