[ Upstream commit aab1f809d7540def24498e81347740a7239a74d5 ] For some unknown reason the regular expression for checkstack only matches three digit numbers starting with the number "3", or any higher number. Which means that it skips any stack sizes smaller than 304 bytes. This makes the checkstack script a bit less useful than it could be. Change the script to match any number. To be filtered out stack sizes can be configured with the min_stack variable, which omits any stack frame sizes smaller than 100 bytes by default.

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.
