Subject: remove dead bdi congestion leftovers
Date: Wed,  1 Jul 2020 11:06:18 +0200
Message-ID: <20200701090622.3354860-1-hch@lst.de> (raw)

Hi Jens,

we have a lot of bdi congestion related code that is left around without
any use.  This series removes it in preparation of sorting out the bdi
lifetime rules properly.
