Waiman Long 8c81ddd2ac ipc: IPCMNI limit check for semmni
For SysV semaphores, the semmni value is the last part of the 4-element
sem number array.  To make semmni behave in a similar way to msgmni and
shmmni, we can't directly use the _minmax handler.  Instead, a special sem
specific handler is added to check the last argument to make sure that it
is limited to the [0, IPCMNI] range.  An error will be returned if this is
not the case.

README

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.
