Those facilities are not overlapping with kgdb though so my point doesnt
apply to them. An in-kernel gdb server sure overlaps/extends kgdb
though.
Btw., perf does meet that definition: it functionally replaces all
facilities that it overlaps/extends - such as Oprofile. 'What about
Oprofile?' was one of the first questions asked when we posted perf.
'What about kgdb?' is the first question to the in-kernel gdb stub
submission here, for similar reasons.
