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
