Subject: [PATCH 05/21] netfilter: nf_tables: add flush field to struct nft_set_iter
Date: Sun, 12 Feb 2017 20:42:37 +0100 [thread overview]
Message-ID: <1486928573-24773-6-git-send-email-pablo@netfilter.org> (raw)
In-Reply-To: <1486928573-24773-1-git-send-email-pablo@netfilter.org>
This provides context to walk callback iterator, thus, we know if the
walk happens from the set flush path. This is required by the new bitmap
set type coming in a follow up patch which has no real struct
nft_set_ext, so it has to allocate it based on the two bit compact
element representation.
