This script computes md5sum of headers in srctree and in objtree. However, when we are building in-tree, we know the srctree and the objtree are the same. That is, we end up with the same computation twice. In fact, the first two lines of kernel/kheaders.md5 are always the same for in-tree builds. Unify the two md5sum calculations. For in-tree builds ($building_out_of_srctree is empty), we check only two directories, "include", and "arch/$SRCARCH/include". For out-of-tree builds ($building_out_of_srctree is 1), we check 4 directories, "$srctree/include", "$srctree/arch/$SRCARCH/include", "include", and "arch/$SRCARCH/include" since we know they are all different.

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.
