Subject: Re: [PATCH 01/16] hashtable: introduce a small and naive hashtable

Hello,
(Sasha, would it be possible to change your MUA so that it breaks long
lines. It's pretty difficult to reply to.)

I think we should stick with INIT_HLIST_HEAD(). It's not a hot path
and we might add, say, debug fields or initialization magics added
later. If this really matters, the right thing to do would be adding
something like INIT_HLIST_HEAD_ARRAY().
Thanks.
