Subject: move the bdi from the request_queue to the gendisk
Date: Mon,  9 Aug 2021 16:17:39 +0200	[thread overview]
Message-ID: <20210809141744.1203023-1-hch@lst.de> (raw)

Hi Jens,

this series moves the pointer to the bdi from the request_queue
to the bdi, better matching the life time rules of the different
objects.
