[PATCH v2 0/2] mm/slub: batch partial slab list operations

[Hao Li]

The loops in get_partial_node_bulk() and __refill_objects_node() perform
individual list operations for each slab. This patchset optimize this.

Patch 1 reduces the number of list operations by processing slabs in
batches, thereby minimizing the time spent inside the critical section.

Patch 2 is a cleanup patch that wraps duplicated code into a helper
function.

Changes in v2:
- Patch 1 apply the same optimization to __refill_objects_node. (Thanks
  Harry and Vlastimil)
- Patch 2 introduce a helper to wraps duplicated code. (Thanks Harry)

Hao Li (2):
  mm/slub: detach and reattach partial slabs in batch
  mm/slub: introduce helper to decrement partial slab count and clear
    flag
