....
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.
