Oops. I just noticed that this patch removes module "libcrc32c".
And this breaks build for Debian kernel v6.12.48.
Previously I tested minimal build using "make localmodconfig".
Now I tried full build of Debian kernel using "dpkg-buildpackage".
And it failed, because some of Debian files reference "libcrc32c",
which is not available.
So, please, don't backport this patch to stable kernels.
I'm sorry.
