Subject: [PATCH v3 18/29] btrfs-progs: delete state_private code
Date: Wed, 23 Nov 2022 17:37:26 -0500	[thread overview]
Message-ID: <1a7227721b908e879cde8563edd4bbb0349ac4cf.1669242804.git.josef@toxicpanda.com> (raw)
In-Reply-To: <cover.1669242804.git.josef@toxicpanda.com>

We used to store random private things into extent_states, but we
haven't done this for a while and there are no users of this code,
simply delete it.
