This explanation for why we're calling syncfs before invoking scrub ought to be captured in a comment preceeding the syncfs call. --D > To fix the above stated problem, this commit invokes syncfs() prior to > executing xfs_scrub. > > Suggested-by: Darrick J.

Tests can create a scenario in which a call to syncfs() issued at the end of the execution of the test script would return an error code. xfs_scrub internally calls syncfs() before starting the actual online consistency check operation. Since this call to syncfs() fails, xfs_scrub ends up returning without performing consistency checks on the test filesystem. This can mask a possible on-disk data structure corruption. To fix the above stated problem, this commit invokes syncfs() prior to executing xfs_scrub. Suggested-by: Darrick J.
