If you know that your kernel modules will only ever be loaded by a newer
kernel, you can disable BASIC_MODVERSIONS to save space. This also
allows easy creation of test modules to seee how tooling will respond to
modules that only have the new format.

This patch series is intended for use alongside the Implement DWARF
modversions series [1] to enable RUST and MODVERSIONS at the same
time.
Elsewhere, we've seen a desire for long symbol name support for LTO
symbol names [2], and the previous series came up [3] as a possible
solution rather than h
Adds a new format for MODVERSIONS which stores each field in a separate
ELF section. This initially adds support for variable length names, but
could later be used to add additional fields to MODVERSIONS in a
backwards compatible way if needed. Any new fields will be ignored by
old user tooling, un

Apologies. Tested before making BASIC_MODVERSIONS default. I've fixed
this locally, and will re-test with the whole stack before resending.

Looks fine. Sent out a proper patch with commit message etc at
https://lore.kernel.org/all/20241122193305.7316-1-torva...@linux-foundation.org/
because it looks good to me.

Oh, that's indeed a nicer syntax. I'll

I'm not loving the "if (0)" with the labels inside of it. But it's the
only way I can see to make a statement expression like this work,
since you can't have a "return" inside of it.
On powerpc for this kind of stuff I have been using do { }
