The Linux kernel is, as a whole, licensed under the GPLv2, but various
parts and pieces are licensed under other compatible licenses and/or
dual-licensed. That picture was much murkier only a few years back, before
the SPDX in the kernel project cleaned up
the licensing information in most of the kernel source by specifying
the licenses, by name rather than boilerplate text, directly
in the files. A recent move to add yet
another license into the mix is encountering some headwinds, but the
license in question has already being used in a few kernel files, and has
been for four years at this point.
