The suggested change would extend the usable range of positive numbers
by one bit only. As many systems are 64 bit this does not seem forward
looking.
I would prefer to have a routine that can handle 64 bit integers with
limits (let's call it proc_doint64vec_minmax) which uses fields extra1
and extra2 of ctl_table as min and max.
Then set xfrm_table[].extra1 = 0 and xfrm_table[].extra2 = UINT_MAX if
you need a result in the u32 range.
Thanks Heinrich. Do you think we can use proc_doulongvec_minmax for
this?
