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

# then resize it. Then we write some data into the image and verify that its

# 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)

# (3) We resize it to 2 MB + 32 kB. (+ 80 kB)
