[PATCH 0/4] mm: Use slab_list list_head instead of lru

From: Tobin C. Harding
Date: Sun Mar 10 2019 - 21:08:30 EST


Currently the slab allocators (ab)use the struct page 'lru' list_head.
We have a list head for slab allocators to use, 'slab_list'.

Clean up all three allocators by using the 'slab_list' list_head instead
of overloading the 'lru' list_head.

Initial patch makes no code changes, adds comments to #endif statements.

Final 3 patches do changes as a patch per allocator, tested by building
and booting (in Qemu) after configuring kernel to use appropriate
allocator. Also build and boot with debug options enabled (for slab
and slub).


thanks,
Tobin.

slub: Add comments to endif pre-processor macros
slub: Use slab_list instead of lru
slab: Use slab_list instead of lru
slob: Use slab_list instead of lru
