Um, what's wrong with the existing s32 and s64 versions that debugfs
already provides?

userspace doesn't know what "int" means for the kernel as it might be
running in 32bit mode with a 64bit kernel.  That is why this isn't a
good idea, so please convert your other patch to use the existing api
and change the variable type in your patch.
