+commit df3cb754d13d2cd5490db9b8d536311f8413a92e upstream.
+
+When expanding a file system from (16TiB-2MiB) to 18TiB, the operation
+exits early which leads to result inconsistency between resize2fs and
+Ext4 kernel driver.
+
+=== before ===
+○ → resize2fs /dev/mapper/thin
+resize2fs 1.45.5 (07-Jan-2020)
+Filesystem at /dev/mapper/thin is mounted on /mnt/test; on-line resizing required
+old_desc_blocks = 2048, new_desc_blocks = 2304
+The filesystem on /dev/mapper/thin is now 4831837696 (4k) blocks long.
