Niltze [Hello]-

Attached is a Reiser4 -enabled Debian packaging hack for Linux 5.14.21-
1 EOL: metztli-reiser4-gcc10-debian-packaging-for-5.14.21-1EOL.patch

For a one off, we can fetch the Debian packaging for 5.14.16-1, the
last one that Debian released, as:

git clone --depth 1 -b debian/5.14.16-1 --single-branch
https://anonscm.debian.org/git/kernel/linux.git

Customize your branch:
git switch -c <new-branch-name>

fetch the 5.14.21 EOL kernel source, etc.
wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.14.21.tar.xz
https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.14.21.tar.sign

Verify:
xz -dc linux-5.14.21.tar.xz | gpg --verify linux-5.14.21.tar.sign -

Make a sym link to feed it to debian:
ln -s linux-5.14.21.tar.xz linux_5.14.21.orig.tar.xz

Change directory:
cd linux

Apply metztli-reiser4-gcc10-debian-packaging-for-5.14.21-1EOL.patch

Debianize your kernel source tree:
debian/rules orig

Apply either of Ed's modified patch for 5.14:
metztli-reiser4-stable-for-5.14.patch.gz
OR
metztli-reiser4-unstable-for-5.14.patch.gz

Of course, we assume -- a priori -- development environment.

Snapshot of the hack in an AMD Ryzen bare metal server:
https://metztli.it/bullseye-reiser5/reiser4-sfrn4-5.14.20-1-amd.png

Hack is currently working in a couple of physical hardware instances
but there are **no implicit nor explicit warranties.**

Best Professional Regards.

-Bug-Debian: https://bugs.debian.org/901492

-We want to enable use of the Android ashmem and binder drivers to
-support Anbox, but they should not be built-in as that would waste
-resources and increase security attack surface on systems that don't
-need them.
-
-Export the currently un-exported symbols they depend on.
