I imagined that, at least in early development phases, developers can
benefit
from the use of a debugger, but it seems that I was wrong. Of course, for
newbies like me, a debugger is essential to understand flow and relations
between kernel code, and I'm happy that this solution is already in the
documentation (unfortunately, not for the version I was using, 4.13). Maybe
the
patch pointed out by Saket can be backported to releases which have the
possibility to enable KALSR, such as 4.9 (LTS) and 4.13 itself (stable)?
