I'm writing the tool for parsing and arranging the data of /proc/lock_stat

this patch to let lock_stat output its information in python expression.

_IF_ we're going to do something like this, I'd much prefer a sane
output format over something that's easily parseble by just one thing.

Does "by just one thing" mean that the ioctl() for format setting
should not be allowed? I have to admit that this patch adds lots of
ugly if and switch statements. If I have to choose just one style
in order to forbid increasing expressions, I'd like to choose
S-expression because it is easy to parse by any language.
