Who is the best inliner of all?

Linus' statement about digital cameras being are more useful than crash dumps for kernel debugging is becouse it's easy to take a picture of an oops and send it out, it's much more work (and therefor fewer people bother) to gather the oops in other ways.

Maybe on production systems, but on test systems you really do want those
oopses stored automatically somewhere (separate disk partition without
filesystem has worked without problems for over a year).
If disk is too risky for Oops information, send them to serial or over
network and have at the other end something that automatically resolves
the oopses properly with kernel debug symbols (which you've separated from
the kernel binary after it's been built).

And finally, it may not be strictly necessary and you could ask people to decipher cryptic messages one way or the other, but debugging the kernel should be as easy as possible. If you want to move the symbol resolution to user space to save kernel memory, you better also move all printk strings to user space as well, as that saves a lot of memory as well.
