2018-05-15xfs: skip scrub xref if corruption already notedDarrick J. Wong1-3/+3
Don't bother looking for cross-referencing problems if the metadata is already corrupt or we've already found a cross-referencing problem. Since we added a helper function for flags testing, convert existing users to use it. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Brian Foster <bfoster@redhat.com>
2018-01-17xfs: cross-reference refcount btree during scrubDarrick J. Wong1-0/+37

2018-01-17xfs: cross-reference reverse-mapping btreeDarrick J. Wong1-0/+65
When scrubbing various btrees, we should cross-reference the records with the reverse mapping btree and ensure that traversing the btree finds the same number of blocks that the rmapbt thinks are owned by that btree.

2018-01-17xfs: cross-reference with the bnobtDarrick J. Wong1-0/+5
When we're scrubbing various btrees, cross-reference the records with the bnobt to ensure that we don't also think the space is free. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>
2018-01-17xfs: introduce scrubber cross-referencing stubsDarrick J. Wong1-0/+12
Create some stubs that will be used to cross-reference metadata records. The actual cross-referencing will be filled in by subsequent patches. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>
