Subject: [PATCH 1/4] drbd: remove a bogus bdi_rw_congested call
Date: Wed,  1 Jul 2020 11:06:19 +0200	[thread overview]
Message-ID: <20200701090622.3354860-2-hch@lst.de> (raw)
In-Reply-To: <20200701090622.3354860-1-hch@lst.de>

bdi_rw_congested returns congestion state, so calling it without
looking at the return value doesn't make much sense.
