Hi all,

After merging the btrfs-fixes tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/btrfs/volumes.c: In function 'btrfs_scan_one_device':
fs/btrfs/volumes.c:1413:55: error: 'bdev_handle' undeclared (first use in this function)
 1413 |         if (btrfs_skip_registration(disk_super, path, bdev_handle->bdev->bd_dev,
      |                                                       ^~~~~~~~~~~
fs/btrfs/volumes.c:1413:55: note: each undeclared identifier is reported only once for each function it appears in

Caused by commit

  cc019bc0d55b ("btrfs: do not skip re-registration for the mounted device")

I have used the btrfs-fixes tree from next-20240315 for today.

This is actually caused by an interaction with commit

  9ae061cf2a46 ("btrfs: port device access to file")

which has been in Linus' tree since March 12 (and linux-next since Feb 26).
