The SPDX-License-Identifiers are growing in the kernel and so grow expression failures and license IDs are used which have no corresponding license text file in the LICENSES directory. Add a script which gathers information from the LICENSES directory, i.e. the various tags in the licenses and exception files and then scans either input from stdin, which it treats as a single file or if started without arguments it scans the full kernel tree. It checks whether the license expression syntax is correct and also validates whether the license identifiers used in the expressions are available in the LICENSES files. scripts/spdxcheck.py -h usage: spdxcheck.py [-h] [-m MAXLINES] [-v] [path [path ...]] SPDX expression checker positional arguments: path Check path or file. If not given full git tree scan. For stdin use "-" optional arguments: -h, --help show this help message and exit -m MAXLINES, --maxlines MAXLINES Maximum number of lines to scan in a file.

Note, this runs single threaded. It scans by default the first 15 lines for a SPDX identifier where the current max inside a top comment is at line 10. But that's going to be faster once the identifiers are all in the first two lines as documented. The python wizards will surely know how to do that smarter and faster, but its at least better than no tool at all.

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. See Documentation/00-INDEX for a list of what is contained in each file. 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.
