The kernel clearly identifies itself as GPL, not LGPL.
"The Linux kernel is released under the GNU General Public License version 2
The footnote for that statement is a link to the COPYING file in the Linux
kernel source, which clearly states GPLv2.
Wikipedia goes on to say that kernel maintainers (doesn't mention who) are of
the opinion that kernel modules are derived works. The FSF says that they are,
but Linus seems to say "sometimes." Linus has also made it clear that binary-
only kernel modules are fine with him.
The kernel does have provision to export symbols (APIs and data structures) to
GPL or OSS-friendly-only licensed kernel modules, and some developers have
taken advantage of that.
There's a collection of Linus' various mailing list posts which state his
opinion and reasoning more clearly:
It's interesting that his viewpoint seems to be pointed more toward drivers
that truly are multi-OS; If a module is built FOR the kernel only, then he
seems to feel that they should be GPL.
But no, the kernel itself is certainly not LGPL.
