Bug Description
The following patch may break user-space, providing an actual ABI change:
UBUNTU: SAUCE: modpost: support arbitrary symbol length in modversion
This is not critical for new releases (also considering that the potential breakage is unlikely to happen, unless some tools/scripts/apps are inspecting modules' internals - likely only kmod tools, that are ok with this change), but for LTS releases it is just safer to prevent adding this change.
Keep in mind that this patch is required to enable Rust support in the generic kernel, but it is not required for hwe kernels, because we do not enable Rust support for them.
