Hi Jan, Kieran,
with the last Linux 5.8-rc6 I have some problems with gdb scripts.
Everything is fine with Linux 5.7.
When I call lx-symbols, I received this error while loading modules
symbols:
(gdb) set python print-stack full
(gdb) target remote :1234
Remote debugging using :1234
arch_atomic_read (v=<optimized out>) at ../arch/x86/kernel/process.c:687
687 trace_cpu_idle_rcuidle(PWR_EVENT_EXIT, smp_processor_id());
(gdb) lx-symbols
loading vmlinux
scanning for modules in /home/stefano/repos/linux_vsock/build-tiny-config
loading @0xffffffffc0169000: /home/stefano/repos/linux_vsock/build-tiny-config/drivers/net/tun.ko

attrs[n]['name'].string(): attrs[n]['address']
gdb.error: There is no member named name.
Error occurred in Python: There is no member named name.
I'll try to bisect.
Thanks,
Stefano

Dig for changes in the data structure (module_sect_attr).

Thanks for the hint, I think I found the problem, I'll send a patch :-)
