Subject: [PATCH 0/5] btrfs: use the super_block as bdev holder

This is a series I've picked up from Christoph, it changes the
block_device's bdev holder from fs_type to the super block.

Here's the original cover letter:
Hi all,

this series contains the btrfs parts of the "remove get_super" from June
that managed to get lost.

I've dropped all the reviews from back then as the rebase against the new
mount API conversion led to a lot of non-trivial conflicts.

Josef kindly ran it through the CI farm and provided a fixup based on that.

Christoph Hellwig (5):
      btrfs: always open the device read-only in btrfs_scan_one_device
      btrfs: call btrfs_close_devices from ->kill_sb
      btrfs: split btrfs_fs_devices.opened
      btrfs: open block devices after superblock creation
      btrfs: use the super_block as holder when mounting file systems
