It was like that for ages... I guess > you can ask glibc guys - the kernel uses void * but glibc uses caddr_t. Does anyone know why glibc uses caddr_t in quotactl(2)? It seems to me that void* would be obviously better, by not needing a cast. - Why was it added in the first place, given the kernel uses void* internally? - Can we change it now to be void*?
