Subject: fixes and cleanups for block_device refcounting v2
Date: Thu, 22 Jul 2021 09:53:53 +0200	[thread overview]
Message-ID: <20210722075402.983367-1-hch@lst.de> (raw)

Hi Jens,

this series fixes up a possible race with the block_device lookup
changes, and the finishes off the conversion to stop using the inode
refcount for block devices.

Changes since v1:
 - clean up btrfs even more by storing a bdev instead of the disk
 - keep a persistent disk reference in the bdev
 - a bunch of cleanups to make the above change easier
