hello Kernelnewbies since folks periodically ask how to contribute to linux, let me humbly propose that you clone this, https://github.com/jimc/linux/tree/dd-classmap-fix-v4g build it, run it inside virtme-ng (a favorite tool), test it using the tools/testing/selftests script. its what Ive posted to LKML for consideration, here. https://lore.kernel.org/lkml/20250803035816.603405-1-jim.cromie@gmail.com/T/... your help in testing this patchset may reduce GregKH's evaluation workload enough that he merges this in this cycle.
