Since I'm one of the people who very much would like best of both worlds,
I do belive Vivek Goyal's concern about the reliability of kdump must be
adressed properly.

I do belive the crash notifier should at least be a list of its own.
  Attaching element to the list proves your are kdump aware - in theory

However:

Conceptually I do not like the princip of implementing crash notifier
as a list simply because for all (our) practical usage there will only
be one element attached to the list anyway.

And as I belive crash notifiers only will be used by a very limited
number of users, I suggested in another mail that a simple

if (function pointer)
   call functon

approach to be used for this special case to keep things very simple.
