Chengming Zhou (12): slub: Reflow ___slab_alloc() slub: Change get_partial() interfaces to return slab slub: Keep track of whether slub is on the per-node partial list slub: Prepare __slab_free() for unfrozen partial slab out of node partial list slub: Introduce freeze_slab() slub: Delay freezing of partial slabs slub: Optimize deactivate_slab() slub: Rename all *unfreeze_partials* functions to *put_partials* slub: Update frozen slabs documentations in the source mm/slub: directly load freelist from cpu partial slab in the likely case mm/slub: remove full list manipulation for non-debug slab mm/slub: remove unused parameter in next_freelist_entry() mm/slub.c | 410 ++++++++++++++++++++++++++---------------------------- 1 file changed, 194 insertions(+), 216 deletions(-) -- 2.25.1
