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). -- Cheers, Stephen Rothwell
