				melifaroAuthorUnsubmitted Done Inline Actions In Linux world there are many variations of kernel/userland version and "old kernel, new userland" is not uncommon.

I agree, it indeed looks weird and I'd rather prefer this (and a bunch of there enum) functionality to embedded in the C standard, but we have what we have ATM. melifaro: In Linux world there are many variations of kernel/userland version and "old kernel, new…
