It does fix my scenario, with the trivial fix of adding bdev-> at the
beginning of that line, ie:

diff --git a/fs/block_dev.c b/fs/block_dev.c
index 993f78c..a8ed344 100644
--- a/fs/block_dev.c
+++ b/fs/block_dev.c

 			}
 			if (bdev->bd_invalidated)
 				rescan_partitions(bdev->bd_disk, bdev);
+			bdev->bd_inode->i_size = (loff_t)get_capacity(disk)<<9;
 		}
 	}
 	bdev->bd_openers++;
