I find that when we mount with journal_async_commit, both the JOURNAL_ASYNC_COMMIT and EXPLICIT_JOURNAL_CHECKSUM flags are set. However, in the error branch, CHECKSUM is checked before ASYNC_COMMIT. As a result, the above inconsistency occurs, and the ASYNC_COMMIT branch becomes dead code that cannot be executed. Therefore, we exchange the positions of the two judgments to make the error msg more accurate.
