Hi,
Is it possible to craft a coccinelle script to find and replace calls (in the kernel) that are
printing pointers using %x.
Perhaps we could easily catch the calls that are casting the pointer within argument list, for example
pr_info("x: %llx\n", (unsigned long long int)ptr);
I'm happy to try and work out how to do it, just chasing a 'yes that is exactly the type of thing
cocci is good at' or a 'no, you are dreaming, perhaps <this tool> can do that'
thanks,
Tobin.

It's possible. Look at coccinelle/demos/format.cocci
This may not be the most well tested part of Coccinelle, so if it is not
doing what you expect, please feel free to complain.
