Commit f8f84b2d ("btrfs: index check-integrity state hash by a dev_t") changed how btrfsic indexes device state. Now we need to access device->bdev->bd_dev, while for degraded mount it's completely possible to have device->bdev as NULL, thus it will trigger a NULL pointer dereference at mount time. Fix it by checking if the device is degraded before accessing device->bdev->bd_dev. There are a lot of other places accessing device->bdev->bd_dev, however the other call sites have either checked device->bdev, or the device->bdev is passed from btrfsic_map_block(), so it won't cause harm.

The C programming language does not allow to use preprocessor statements inside macro arguments (pr_info() is defined as a macro). Hence rework the pr_info() statement in btrfs_print_mod_info() such that it becomes compliant. This patch allows tools like sparse to analyze the BTRFS source code.

Currently this function takes the root as an argument only to get the log_root from it. Simplify this by directly passing the log root from the caller. Also eliminate the fs_info local variable, since it's used only once, so directly reference it from the transaction handle. Signed-off-by:

The logic to check if the inode is already in the log can now be simplified since we always wait for the ordered extents to complete before deciding whether the inode needs to be logged. The big comment about it can go away too. CC: Filipe Manana <fdmanana@suse.com> Suggested-by:
