Oh well, ok, will do next time.

We use it in many places, one could say the kernel isn't written in C
anyway:
[acme@zoo linux]$ find . -name "*.[ch]" | xargs grep '?:' | cut -d'/' -f -2 | sort | uniq -c | sort -nr
189 ./drivers
45 ./arch
33 ./crypto
30 ./fs
25 ./net
23 ./kernel
22 ./tools
9 ./sound
8 ./include
5 ./security
5 ./mm
3 ./block
2 ./lib
1 ./scripts
1 ./ipc
[acme@zoo linux]$
Other than that, are you ok with the change?
