fixed memory bytes

[mohit verma]

hi all,
i have seen many places in  kernel where the variables specially the
structures should be of  fixed size independent of the architecture. i went
through the  definitions of them  but dint  get  clearly (or frankly  say
...dint get them even a bit) .


so ,can please someone  help me to understand this??


thanks in advance for help........
