If you feel you actually learn something by doing the Eudyptula
Challenge, then good for you, and by all means continue doing so. As I
mentioned, I know almost zero about it, but can say for sure that
cleanups alone won't get you very far in the community and you will
probably get bored sooner or later -- which is unfortunate as kernel
hacking fascinating.

There are plenty of bugs out there, and not so hard to find -- just push
some module/filesystem/subsystem/testcase hard enough to make it do
things it shouldn't. Run linux-next on trinity and fix/report the bugs,
etc.

imho testing and reading other people's patches is perhaps the best way
to do useful things, get acquainted with the code and get experience
with lkml and the process behind kernel development.

Probably not, unless it's a tree-wide change.

Hope this helps,
