Hi,

I'm looking at the implementation of `keyctl_capabilities` in the `next`
branch and it's not clear if `buflen` is the size of the memory pointed
to by `buffer` in array size or in byte size by its documentation. It
seems to be the size in bytes by the code (the &3) could probably
warrant a comment to make it clearer that it is related to
sizeof(unsigned int) here). This seems very odd to me, or is it just a
common kernel pattern I haven't seen before?

Thanks,

--Ben
