SPDX license identifiers in the Linux kernel
Some of you have already noticed that this started in 2016
but as of 4.14, we had a major breakthrough and cleanup
of all the files without a license reference all had SDPX identifiers
added to them.
There are some good writeups of the work emerging.
LWN has an excellent summary with links to more references at:
There's also a good blog by one of the kernel developers
from Samsung explaining how to add the identifiers as well
that came out last week.
Some other excellent documentation that has emerged
including how to integrate SPDX one liners into a project
is available at: https://reuse.software/practices/ which the linux kernel
developers have consulted and worked with for the kernel.
