Nit-pick: here and below in this file, please try to keep max line
length at 80 characters. I know it's not mandatory anymore, but I'd
personally prefer it to be that away (otherwise it's not consistent
with most of lines that are 80 char long). It's easy to spot that with
"checkpatch.pl --strict".
