+# Generally, we create some image with or without existing preallocation and

+# size does not change if we have used preallocation.
+
+# With a cluster size of 512 B, one L2 table covers 64 * 512 B = 32 kB.
+# One cluster of the L1 table covers 64 * 32 kB = 2 MB.
+# There are multiple cases we want to test:
+# (1) Grow an image without having to allocate a new L2 table.
+# (2) Grow an image, having to allocate a new L2 table.
+# (3) Grow an image, having to grow the L1 table.
+# Therefore, we create an image that is 48 kB below 2 MB. Then:
+# (1) We resize it to 2 MB - 32 kB. (+ 16 kB)
+# (2) We resize it to 2 MB.         (+ 48 kB)
