I agree with the target.
I understand there is a person who is the neat paranoiac that it
doesn't want to leave the code for debugging for a final code. If
it is a situation in which the code for debugging without united
interfaces lies scattered, the opinion might be correct.
It is an effective method only to set up the marker if the code
for debugging without united interfaces can be appropriately set
up with the marker.
I think that the mechanism that can offer both non-debugging and
debugging information to the generic pursuit mechanism to permit
the analysis of the entire kernel system in the meaning of
obtaining dynamic information for a long time not obtained by a
static necropsy by kdump is indispensable in a mission-critical
system.
