Hi David,

I don't know the larger context of this patch (and am not follwing
filesystem related work in general), but at least from the xt_hashlimit
point of view this of course looks fine.  We can always wrap direct
accesses to structure members behind an API call.

For consistency reasons 'proc_get_name()' might be a better name than
get_proc_name(), but that's probably a matter of taste.

Pleaes note that I'm only the original author but not the active
maintainer of the xt_hashlimit (formerly ipt_hashlimit) code.

Regards,
	Harald
