Darrick J. Wong c473a3320b xfs: stagger the starting AG of scrub iscans to reduce contention ... Online directory and parent repairs on parent-pointer equipped filesystems have shown that starting a large number of parallel iscans causes a lot of AGI buffer contention. Try to reduce this by making it so that iscans scan wrap around the end of the filesystem, and using a rotor to stagger where each scanner begins. Surprisingly, this boosts CPU utilization (on the author's test machines) from effectively single-threaded to 160%. Not great, but see the next patch. Signed-off-by: Darrick J.
