2019-04-30	xfs: add online scrub for superblock counters	Darrick J. Wong	1	-0/+1
	Teach online scrub how to check the filesystem summary counters. We use the incore delalloc block counter along with the incore AG headers to compute expected values for fdblocks, icount, and ifree, and then check that the percpu counter is within a certain threshold of the expected value. This is done to avoid having to freeze or otherwise lock the filesystem, which means that we're only checking that the counters are fairly close, not that they're exactly correct.

2019-04-16	xfs: scrub should only cross-reference with healthy btrees	Darrick J. Wong	1	-0/+60
	Skip cross-referencing with a btree if the health report tells us that it's known to be bad. This should reduce the dmesg spew considerably. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Dave Chinner <dchinner@redhat.com>
