xfs: use separate btree cursor cache for each btree typexfs-merge-5.16_2021-10-19
Now that we have the infrastructure to track the max possible height of
each btree type, we can create a separate slab cache for cursors of each
type of btree. For smaller indices like the free space btrees, this
means that we can pack more cursors into a slab page, improving slab
utilization.
