[$] Hash-based module integrity checking

On January 20, Thomas Weißschuh shared a new

patch set implementing an alternate method for checking the integrity of
loadable kernel modules. This mechanism, which checks module integrity based
on hashes computed at build time instead of using cryptographic signatures,
could enable reproducible kernel builds in more contexts. Several distributions
have already expressed interest in the patch set if Weißschuh can get it
into the kernel.
