The work for 'const struct bin_attribute' [1] was merged into linux-next but did not include updates to the lx-symbols code. So it now fails with the following error: Python Exception <class 'gdb.error'>: There is no member named nsections. Error occurred in Python: There is no member named nsections. Restore its functionality by aligning it with those changes on kernel/module/sysfs.c.
