....
Hmmm... 21 is infinite? Interesting.
I find that it would be interesting to me personally if the kernel was
smart enough to spit out something like:
Oct 15 16:24:38 larrylap kernel: [<c0131210>] find_[...]+0xa0/0xd0
[21 times]
(of course, with find_usage_backwards spelled out)
After all, what if it's practical that a specific recursion would run
3000 times and it gets caught at 5000 times? ("f**king bad design")
Just a pet peeve of mine though.

Lock-validator code uses recursive functions to verify lock
dependencies. And one should have some limit for recursive
function,otherwise stack may get overflowed. So at any case 20 is the
max depth for this recursive functions. But this value doesn't scale up
for 16-way or 32-way SMP systems. Hence this bug.
