Modify the loopback size in the blockfile snapshotter test setup. Set the loopback size to 16MB when the page size is greater than 4096. This prevents smaller storage devices from running out of free space while the test is running. Addresses issue #8767.

Hi @Jenkins-J. Thanks for your PR.

I'm waiting for a containerd member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

@Jenkins-J would you mind to share the test result? just wonder that 16MiB is good enough for the test. Thanks

@fuweid Here are the test results from the blockfile snapshotter testsuite. I ran the test with go test -v -test.root -run TestBlockfile. If there are any other tests you'd like me to run or a better way to execute the testsuite, let me know.
