Is the environment or configuration incorrect? How should I fix it?
test-all runs all tests including those marked as "unstable". I'd recommend using just make test to run only "stable" tests. Unstable tests are randomly failing and we can't do nothing about that because the problem isn't in our code (or at least we think it isn't). Bcache is unfortunately notoriously broken. We are actually discussing removing the functionality in the next major version of libblockdev. The NTFS test case was removed in the latest release because it was testing ntfs-3g behaviour that changes between versions and also depends on some build time configuration that is different in different distributions. tl;dr you can ignore these failures.
Thank you for your reply， which solved my question.
